Generally if a role is granted membership to another role with NOINHERIT
they must use SET ROLE to access the privileges of that role, however
with predefined roles the membership and privilege is conflated. Fix that
by replacing is_member_of_role with has_privs_for_role for predefined
roles. Patch does not remove is_member_of_role from acl.h, but it does
add a warning not to use that function for privilege checking. Not
backpatched based on hackers list discussion.

Clarify libpq.sgml's description of service file locations and
semantics. Avoid use of backtick'ed pg_config calls to describe
paths; that doesn't work on Windows, and even on Unix it's an
idiom that not all readers may be instantly familiar with.
Don't overspecify the locations of include files, instead writing
only as much as you'd use in #include directives. The previous text
in these places was incorrect for some installations, depending on
where "postgresql" is in the install path.
Our convention for referencing the user's home directory seems
to be "~", so change the one place that spelled it "$HOME".
install-windows.sgml follows the platform convention of spelling
file paths with "\", so change the one place that used "/".

This changes our catalog and view descriptions to use a style inspired
by the new format for function/operator tables: each table entry is
formatted roughly like a <varlistentry>, with the column name and type
on the first line and then an indented description. This provides much
more room for expansive descriptions than we had before, and thereby
eliminates a passel of PDF build warnings.

Access to this module is granted to the pg_monitor role, not
pg_read_all_stats. (Given the view's performance impact,
it seems wise to be restrictive, so I think this was the
correct decision --- and anyway it was clearly intentional.)

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.

For DocBook XML compatibility, don't use SGML empty tags (</>) anymore,
replace by the full tag name. Add a warning option to catch future
occurrences.

Three nologin roles with non-overlapping privs are created by default
* pg_read_all_settings - read all GUCs.
* pg_read_all_stats - pg_stat_*, pg_database_size(), pg_tablespace_size()
* pg_stat_scan_tables - may lock/scan tables
Top level role - pg_monitor includes all of the above by default, plus others

The new column shows how many backends have a buffer pinned. That can
be useful during development or to diagnose production issues
e.g. caused by vacuum waiting for cleanup locks.
To handle upgrades transparently - the extension might be used in
views - deal with callers expecting the old number of columns.

Block elements with verbatim formatting (literallayout, programlisting,
screen, synopsis) should be aligned at column 0 independent of the surrounding
SGML, because whitespace is significant, and indenting them creates erratic
whitespace in the output. The CSS stylesheets already take care of indenting
the output.
Assorted markup improvements to go along with it.
of shared or nailed system catalogs. This has two key benefits:
* The new CLUSTER-based VACUUM FULL can be applied safely to all catalogs.
* We no longer have to use an unsafe reindex-in-place approach for reindexing
shared catalogs.
CLUSTER on nailed catalogs now works too, although I left it disabled on
shared catalogs because the resulting pg_index.indisclustered update would
only be visible in one database.
Since reindexing shared system catalogs is now fully transactional and
crash-safe, the former special cases in REINDEX behavior have been removed;
shared catalogs are treated the same as non-shared.
This commit does not do anything about the recently-discussed problem of
deadlocks between VACUUM FULL/CLUSTER on a system catalog and other
concurrent queries; will address that in a separate patch. As a stopgap,
parallel_schedule has been tweaked to run vacuum.sql by itself, to avoid
such failures during the regression tests.
to ensure that the resulting webpages have predictable URLs, instead of
ever-changing numeric IDs. The new contrib docs were the biggest
offender, but some old stuff had the problem too. Also, rename a couple
of new contrib sgml files for consistency's sake.
