the default.  This setting enables constraint exclusion checks only for
appendrel members (ie, inheritance children and UNION ALL arms), which are
the cases in which constraint exclusion is most likely to be useful.  Avoiding
the overhead for simple queries that are unlikely to benefit should bring
the cost down to the point where this is a reasonable default setting.
Per today's discussion.

debug_query_string;  this allows current_query() to be more accurate;
docs updated;  per idea from Tom

OutputFunctionCall, and friends.  This allows SPI-using functions to invoke
datatype I/O without concern for the possibility that a SPI-using function
will be called (which could be either the I/O function itself, or a function
used in a domain check constraint).  It's a tad ugly, but not nearly as ugly
as what'd be needed to make this work via retail insertion of push/pop
operations in all the PLs.

This reverts my patch of 2007-01-30 that inserted some retail SPI_push/pop
calls into plpgsql; that approach only fixed plpgsql, and not any other PLs.
But the other PLs have the issue too, as illustrated by a recent gripe from
Christian Schröder.

Back-patch to 8.2, which is as far back as this solution will work.  It's
also as far back as we need to worry about the domain-constraint case, since
earlier versions did not attempt to check domain constraints within datatype
input.  I'm not aware of any old I/O functions that use SPI themselves, so
this should be sufficient for a back-patch.

'query_string' from current_query().

not include postgres.h nor anything else it doesn't directly need.  Add
#includes to calling files as needed to compensate.  Per my proposal of
yesterday.

This should be noted as a source code change in the 8.4 release notes,
since it's likely to require changes in add-on modules.

to pass the full username@realm string to the authentication instead of
just the username. This makes it possible to use pg_ident.conf to authenticate
users from multiple realms as different database users.

authentication options to be set in pg_hba.conf on a per-line basis, to
override the defaults set in postgresql.conf.

like previous patch did.

Per note from Tom Lane

hardcoded paths for SSL rootcert/crl/clientcert/key.

consistent. Currently, in csvlog, vxid of an auxiliary process isn't
displayed. On the other hand, in stderr/syslog, invalid vxid (-1/0) of
that is displayed.

Per Nathan Boley.

Fix \do and trigger display for the patch too.

like \dt does, in that it requires a \dXS to see system items.

same way the unix build now does.

various documentation, since those lists are now dead/deprecated.
Point to pgsql-bugs and/or pgsql-hackers as appropriate.

particular this allows EmitWarningsOnPlaceholders messages to show up in the
postmaster log by default.  Update elog.h comment to make it clearer what INFO
is for, and fix one example in the SGML docs that was misusing it.  Per my
gripe of yesterday.

where there's no limit on the size of datum we'll try to compress.
Other 8.4 tweaks to the behavior remain in place.  Per discussion.

earlier than all the other sizeof checks, and it certainly fails to follow
the order suggested at the file head.  Rearrange.

If the table was smaller than REL_TRUNCATE_FRACTION (= 16) pages, we always
tried to acquire AccessExclusiveLock on it even if there was no empty pages
at the end.

Report by Simon Riggs. Back-patch all the way to 7.4.
