The link to the NIST web page about DES standards leads to nowhere, and
according to archive.org has been forwarded to an unrelated page for
many years. Therefore, just remove that link. More up to date
information can be found via Wikipedia, for example.
The syntax summary previously failed to clarify that the first
argument is also optional. The textual description did mention it,
but all the way at the bottom. It fits better with the command
overview, so move it there, and fix the summary also.
Back-patch to 9.4 where \pset without arguments was supported.

Errors detected using Topy (https://github.com/intgr/topy), all
changes verified by hand and some manual tweaks added.

Individual changes backpatched, where applicable, as far as 9.0.
Cause the path extraction operators to return their lefthand input,
not NULL, if the path array has no elements. This seems more consistent
since the case ought to correspond to applying the simple extraction
operator (->) zero times.
Cause other corner cases in field/element/path extraction to return NULL
rather than failing. This behavior is arguably more useful than throwing
an error, since it allows an expression index using these operators to be
built even when not all values in the column are suitable for the
extraction being indexed. Moreover, we already had multiple
inconsistencies between the path extraction operators and the simple
extraction operators, as well as inconsistencies between the JSON and
JSONB code paths. Adopt a uniform rule of returning NULL rather than
throwing an error when the JSON input does not have a structure that
permits the request to be satisfied.
Back-patch to 9.4. Update the release notes to list this as a behavior
change since 9.3.
As 'ALTER TABLESPACE .. MOVE ALL' really didn't change the tablespace
but instead changed objects inside tablespaces, it made sense to
rework the syntax and supporting functions to operate under the
'ALTER (TABLE|INDEX|MATERIALIZED VIEW)' syntax and to be in
tablecmds.c.
Pointed out by Alvaro, who also suggested the new syntax.
Back-patch to 9.4.
The aboriginal sample placed connection parameters in
groupOfUniqueNames/uniqueMember. OpenLDAP, at least as early as version
2.4.23, rejects uniqueMember entries that do not conform to the syntax
for a distinguished name. Use device/description, which is free-form.
Back-patch to 9.4 for web site visibility.
Oversight in commit 7cbe57c34d.
Back-patch to 9.4, where that commit first appeared. In passing,
release-note the FDW API postcondition change from the same commit.
The old text explained what happened if we didn't have working int64
arithmetic. Since that case has been explicitly rejected by configure
since 8.4.3, documenting it in the 9.x branches can only produce confusion.
Commit f30015b6d7 made this happen for
timestamp and timestamptz, but it seems pretty inconsistent to not
do it for simple dates as well.
(In passing, I re-pgindent'd json.c.)
Previously only CREATE_REPLICATION_SLOT was exposed as an index term.
That's odd and there is no reason not to add index terms for other
replication commands.
Back-patch to 9.4.
Update the notes to include commits through today, and do a lot of
wordsmithing and markup adjustment. Notably, don't use <link> where <xref>
will do; since we got rid of the text-format HISTORY file, there is no
longer a reason to avoid <xref>.
The new DISCARD SEQUENCES option was inadequately described, and hadn't
been mentioned at all in the initial Description paragraph. Rather than
rectifying the latter the hard way, it seemed better to rewrite the
description as a summary, instead of having it basically duplicate
statements made under Parameters. Be more consistent about the ordering
of the options, too.
The upstream stylesheets for man output insert a *roff comment for an
occurrence of an indexterm, for reasons that have apparently been lost
in history. This, however, is done incorrectly and causes some
formatting problems. This hasn't been an issue until now, but the
reorganization of indexterm elements inside variablelists has triggered
this issue.
The upstream fix (http://sourceforge.net/p/docbook/bugs/1340/) is to
drop indexterms altogether in man output, and so we'll do the same here.
FreeBSD hasn't made any use of kern.ipc.semmap since 1.1, and newer
releases reject attempts to set it altogether; so stop recommending
that it be adjusted. Per bug #11161.
Back-patch to all supported branches. Before 9.3, also incorporate
commit 7a42dff47, which touches the same text and for some reason
was not back-patched at the time.
This option is equivalent to --slot option which pg_receivexlog has
already supported, which specifies the replication slot to use for
WAL streaming. pg_recvlogical has already supported both options,
and this commit makes pg_receivexlog consistent with pg_recvlogical
regarding the slot option.
Back-patch to 9.4 where the slot option was added.
Michael Paquier
The initialization fork was added in 9.1, but has not been taken into
consideration in documents of get_raw_page function in pageinspect and
storage layout. This commit fixes those oversights.
get_raw_page can read not only a table but also an index, etc. So it
should be documented that the function can read any relation. This commit
also fixes the document of pageinspect that way.
Back-patch to 9.1 where those oversights existed.

The user documentation was vague and not entirely accurate about how
we treat domain inputs for ambiguous operators/functions. Clarify
that, and add an example and some commentary. Per a recent question
from Adam Mackler.
It's acted like this ever since we added domains, so back-patch
to all supported branches.
Fix an obvious typo in json_build_object()'s complaint about invalid
number of arguments, and make the errhint a bit more sensible too.
Per discussion about how to word the improved hint, change the few places
in the documentation that refer to JSON object field names as "names" to
say "keys" instead, since that's what we've said in the vast majority of
places in the docs. Arguably "name" is more correct, since that's the
terminology used in RFC 7159; but we're stuck with "key" in view of the
naming of json_object_keys() so let's at least be self-consistent.
I adjusted a few code comments to match this as well, and failed to
resist the temptation to clean up some odd whitespace choices in the
same area, as well as a useless duplicate PG_ARGISNULL() check. There's
still quite a bit of code that uses the phrase "field name" in non-user-
visible ways, so I left those usages alone.
- Capitalize titles consistently.
- Fix some grammar.
- Group "Obtaining Information About an Error" under "Trapping Errors",
but make "Obtaining the Call Stack Context Information" its own
section, since it's not about errors.
Previously the duplicated paragraphs were used next to each other
in the document to demonstrate that the changes in the stream
were not consumed by pg_logical_slot_peek_changes function.
But some users misunderstood that the duplication of the same
paragraph was just typo. So this commit rewords the sentence in
the latter paragraph for less confusing.
Christoph Moench-Tegeder
The documentation of ALTER TABLESPACE ... MOVE was added without any
markup, not even paragraph breaks. Fix that, and clarify the text in a
few places.
Break the list of available options into an <itemizedlist> instead of
inline sentences. This is mostly motivated by wanting to ensure that the
cross-references to the FSM and VM docs don't cross page boundaries in PDF
format; but it seems to me to read more easily this way anyway. I took the
liberty of editorializing a bit further while at it.
Per complaint from Magnus about 9.0.18 docs not building in A4 format.
Patch all active branches so we don't get blind-sided by this particular
issue again in future.
~/.pgpass is a sound choice everywhere, and "peer" authentication is
safe on every platform it supports. Cease to recommend "trust"
authentication, the safety of which is deeply configuration-specific.
Back-patch to 9.0, where pg_upgrade was introduced.
The old name wasn't very descriptive as of actual contents of the
directory, which are historical snapshots in the snapshots/
subdirectory and mappingdata for rewritten tuples in
mappings/. There's been a fair amount of discussion what would be a
good name. I'm settling for pg_logical because it's likely that
further data around logical decoding and replication will need saving
in the future.
Also add the missing entry for the directory into storage.sgml's list
of PGDATA contents.
Bumps catversion as the data directories won't be compatible.
Backpatch to 9.4, which I missed to do as Michael Paquier luckily
noticed. As there already has been a catversion bump after 9.4beta1,
there's no reasons for having 9.4 diverge from master.
The "false" case was really quite useless since all it did was to throw
an error; a definition not helped in the least by making it the default.
Instead let's just have the "true" case, which emits nested objects and
arrays in JSON syntax. We might later want to provide the ability to
emit sub-objects in Postgres record or array syntax, but we'd be best off
to drive that off a check of the target field datatype, not a separate
argument.
For the functions newly added in 9.4, we can just remove the flag arguments
outright. We can't do that for json_populate_record[set], which already
existed in 9.3, but we can ignore the argument and always behave as if it
were "true". It helps that the flag arguments were optional and not
documented in any useful fashion anyway.
These should not have existed to begin with, but there was apparently some
misunderstanding of the purpose of the opr_sanity regression test item
that checks for operator implementation functions with their own comments.
The idea there is to check for unintentional violations of the rule that
operator implementation functions shouldn't be documented separately
.... but for these functions, that is in fact what we want, since the
variadic option is useful and not accessible via the operator syntax.
Get rid of the extra pg_proc entries and fix the regression test and
documentation to be explicit about what we're doing here.
7380b63 changed log_filename so that epoch was not appended to it
when no format specifier is given. But the example of CSV log file name
with epoch still left in log_filename document. This commit removes
such obsolete example.
This commit also documents the defaults of log_directory and
log_filename.
Backpatch to all supported versions.
Christoph Berg
By using curly braces, the template had specified that one of
"NOT DEFERRABLE", "INITIALLY IMMEDIATE", or "INITIALLY DEFERRED"
was required on any CREATE TRIGGER statement, which is not
accurate. Change to square brackets makes that optional.
Backpatch to 9.1, where the error was introduced.
