The documentation neglected to explain its behavior in a script file
(it only ends execution of the script, not psql as a whole), and failed
to mention the long form \quit either.
This mode still exists for backwards compatibility, making
sslmode=require the same as sslmode=verify-ca when the file is present,
but not causing an error when it isn't.
Per bug 6189, reported by Srinivas Aji
This example wasn't updated when we changed the behavior of bpcharlen()
in 8.0, nor when we changed the number of parameters taken by the bpchar()
cast function in 7.3. Per report from lsliang.
Somebody added a cross-reference to shared_preload_libraries, but wrote the
wrong variable name when they did it (and didn't bother to make it a link
either).
Spotted by Christoph Anton Mitterer.
In the example for decode(), show the bytea result in hex format,
since that's now the default. Use an E'' string in the example for
quote_literal(), so that it works regardless of the
standard_conforming_strings setting. On the functions-for-binary-strings
page, leave the examples as-is for readability, but add a note pointing out
that they are shown in escape format. Per comments from Thom Brown.
Also, improve the description for encode() and decode() a tad.
Backpatch to 9.0, where bytea_output was introduced.
Somehow, column rolconfig got removed from the documentation of the
pg_roles view in the 9.0 cycle, although the column is actually still
there. In 9.1, we'd also forgotten to document the rolreplication column.
Spotted by Sakamoto Masahiko.
This is a dangerous example to provide because on machines with GNU cp,
it will silently do the wrong thing and risk archive corruption. Worse,
during the 9.0 cycle somebody "improved" the discussion by removing the
warning that used to be there about that, and instead leaving the
impression that the command would work as desired on most Unixen.
It doesn't. Try to rectify the damage by providing an example that is safe
most everywhere, and then noting that you can try cp -i if you want but
you'd better test that.
In back-patching this to all supported branches, I also added an example
command for Windows, which wasn't provided before 9.0.
... when talking about how good they are in replacement of bulk DELETE
in partitioned setups.
The original wording was a bit confusing.
Per an observation from David Wheeler.
The previous wording wasn't explicit enough, which could misled readers
into thinking that the locks acquired are more restricted in nature than
they really are. The resulting optimism can be damaging to morale when
confronted with reality, as has been observed in the field.

This is more consistent with what we do elsewhere, and hopefully avoids
creating the perception that current_schemas takes no arguments.
As suggested by Brendan Jurd
The documentation of the columns collection_type_identifier and
dtd_identifier was wrong. This effectively reverts commits
8e1ccad519 and
57352df66d and updates the name
array_type_identifier (the name in SQL:1999) to
collection_type_identifier.
closes bug #5926
Apparently sane-looking penalty code might return small negative values,
for example because of roundoff error. This will confuse places like
gistchoose(). Prevent problems by clamping negative penalty values to
zero. (Just to be really sure, I also made it force NaNs to zero.)
Back-patch to all supported branches.

There was already one recommendation in the documentation about writing
C functions to ensure padding bytes are zeroes, but make it stronger.
Also fix an example that was still using direct assignment to a varlena
length word, which no longer works since the varvarlena changes.
