dce988145f Doc: fix old oversights in GRANT/REVOKE documentation.
The GRANTED BY clause in GRANT/REVOKE ROLE has been there since 2005
but was never documented.  I'm not sure now whether that was just an
oversight or was intentional (given the limited capability of the
option).  But seeing that pg_dumpall does emit code that uses this
option, it seems like not documenting it at all is a bad idea.

Also, when we upgraded the syntax to allow CURRENT_USER/SESSION_USER
as the privilege recipient, the role form of GRANT was incorrectly
not modified to show that, and REVOKE's docs weren't touched at all.

Although I'm not that excited about GRANTED BY, the other oversight
seems serious enough to justify a back-patch.

afc4a78a30 Refactor documentation about privileges to centralize the info.
Expand section 5.6 "Privileges" to include the full definition of
each privilege type, and an explanation of aclitem privilege displays,
along with some helpful summary tables.  Most of this material came
out of the GRANT reference page, although some of it is new.
Adjust a bunch of links that were pointing to GRANT to point to 5.6.

e4128ee767 SQL procedures
This adds a new object type "procedure" that is similar to a function
but does not have a return type and is invoked by the new CALL statement
instead of SELECT or similar.  This implementation is aligned with the
SQL standard and compatible with or similar to other SQL implementations.

This commit adds new commands CALL, CREATE/ALTER/DROP PROCEDURE, as well
as ALTER/DROP ROUTINE that can refer to either a function or a
procedure (or an aggregate function, as an extension to SQL).  There is
also support for procedures in various utility commands such as COMMENT
and GRANT, as well as support in pg_dump and psql.  Support for defining
procedures is available in all the languages supplied by the core
distribution.

While this commit is mainly syntax sugar around existing functionality,
future features will rely on having procedures as a separate object
type.

3c49c6facb Convert documentation to DocBook XML
Since some preparation work had already been done, the only source
changes left were changing empty-element tags like <xref linkend="foo">
to <xref linkend="foo"/>, and changing the DOCTYPE.

The source files are still named *.sgml, but they are actually XML files
now.  Renaming could be considered later.

In the build system, the intermediate step to convert from SGML to XML
is removed.  Everything is build straight from the source files again.
The OpenSP (or the old SP) package is no longer needed.

The documentation toolchain instructions are updated and are much
simpler now.

1ff01b3902 Convert SGML IDs to lower case
IDs in SGML are case insensitive, and we have accumulated a mix of upper
and lower case IDs, including different variants of the same ID.  In
XML, these will be case sensitive, so we need to fix up those
differences.  Going to all lower case seems most straightforward, and
the current build process already makes all anchors and lower case
anyway during the SGML->XML conversion, so this doesn't create any
difference in the output right now.  A future XML-only build process
would, however, maintain any mixed case ID spellings in the output, so
that is another reason to clean this up beforehand.

aefeb68741 Allow referring to functions without arguments when unique
In DDL commands referring to an existing function, allow omitting the
argument list if the function name is unique in its schema, per SQL
standard.

This uses the same logic that the regproc type uses for finding
functions by name only.

bb4eefe7bf doc: Improve DocBook XML validity
DocBook XML is superficially compatible with DocBook SGML but has a
slightly stricter DTD that we have been violating in a few cases.
Although XSLT doesn't care whether the document is valid, the style
sheets don't necessarily process invalid documents correctly, so we need
to work toward fixing this.

This first commit moves the indexterms in refentry elements to an
allowed position.  It has no impact on the output.

6ef2448796 Fix a whitespace issue with the man pages
There is what may actually be a mistake in our markup.  The problem is
in a situation like

<para>
 <command>FOO</command> is ...

there is strictly speaking a line break before "FOO".  In the HTML
output, this does not appear to be a problem, but in the man page
output, this shows up, so you get double blank lines at odd places.

So far, we have attempted to work around this with an XSL hack, but
that causes other problems, such as creating run-ins in places like

<acronym>SQL</acronym> <command>COPY</command>

So fix the problem properly by removing the extra whitespace.  I only
fixed the problems that affect the man page output, not all the
places.

6dcce3985b Remove unnecessary xref endterm attributes and title ids
The endterm attribute is mainly useful when the toolchain does not support
automatic link target text generation for a particular situation.  In  the
past, this was required by the man page tools for all reference page links,
but that is no longer the case, and it now actually gets in the way of
proper automatic link text generation.  The only remaining use cases are
currently xrefs to refsects.

d129255077 Set SQL man pages to be section 7 by default, and only transform them to
another section if required by the platform (instead of the old way of
building them in section "l" and always transforming them to the

This speeds up the installation on common platforms, and it avoids some
funny business with the man page tools and build process.

e81c138e18 Update reference documentation on may/can/might:
Standard English uses "may", "can", and "might" in different ways:

        may - permission, "You may borrow my rake."

        can - ability, "I can lift that log."

        might - possibility, "It might rain today."

Unfortunately, in conversational English, their use is often mixed, as
in, "You may use this variable to do X", when in fact, "can" is a better
choice.  Similarly, "It may crash" is better stated, "It might crash".

7bae5a289c Get rid of the separate RULE privilege for tables: now only a table's owner
can create or modify rules for the table.  Do setRuleCheckAsUser() while
loading rules into the relcache, rather than when defining a rule.  This
ensures that permission checks for tables referenced in a rule are done with
respect to the current owner of the rule's table, whereas formerly ALTER TABLE
OWNER would fail to update the permission checking for associated rules.
Removal of separate RULE privilege is needed to prevent various scenarios
in which a grantee of RULE privilege could effectively have any privilege
of the table owner.  For backwards compatibility, GRANT/REVOKE RULE is still
accepted, but it doesn't do anything.  Per discussion here:

clause implicitly whenever one is not given explicitly.  Remove concept
of a schema having an associated tablespace, and simplify the rules for
selecting a default tablespace for a table or index.  It's now just
(a) explicit TABLESPACE clause; (b) default_tablespace if that's not an
empty string; (c) database's default.  This will allow pg_dump to use
SET commands instead of tablespace clauses to determine object locations
(but I didn't actually make it do so).  All per recent discussions.

4b2dafcc0b Align GRANT/REVOKE behavior more closely with the SQL spec, per discussion
of bug report #1150.  Also, arrange that the object owner's irrevocable
grant-option permissions are handled implicitly by the system rather than
being listed in the ACL as self-granted rights (which was wrong anyway).
I did not take the further step of showing these permissions in an
explicit 'granted by _SYSTEM' ACL entry, as that seemed more likely to
bollix up existing clients than to do anything really useful.  It's still
a possible future direction, though.

8545482947 When a superuser does GRANT or REVOKE on an object he doesn't own,
process the command as though it were issued by the object owner.
This prevents creating weird scenarios in which the same privileges
may appear to flow from different sources, and ensures that a superuser
can in fact revoke all privileges if he wants to.  In particular this
means that the regression tests work when run by a superuser other than
the original bootstrap userid.  Per report from Larry Rosenman.
