rewritten into another kind of statement, for example if an INSERT is
rewritten into an UPDATE.
Back-patch to 8.3 and 8.2. For HEAD, Tom suggested inventing a new
SPI_OK_REWRITTEN return code, but that's not a backportable solution. I'll
do that as a separate patch, this patch will do as a stopgap measure for HEAD
too in the meanwhile.

It's not possible to do CREATE DATABASE inside a transaction, so previously
we just got a server error instead.
Backpatch to 8.2, which is where the -1 feature appeared.

now always use the system username as the default, and not try to pick it up
from the kerberos ticket.
This fixes the spurious error messages that show up on kerberos-enabled builds
when not actually using kerberos, and puts it in line with how other authentication
methods work.

fillRelOptions routine that stores the parsed values in the struct using a
table-based approach. Per Tom suggestion. Also remove the "continue"
in HANDLE_*_RELOPTION macros, which were useless and in spirit they were
assuming too much of how the macros were going to be used. (Note that these
macros are now unused, but the intention is to introduce some usage in a
future autovacuum patch, which is why they weren't completely removed.)
Also, do not call the string validation routine when not validating. It seems
less error-prone this way, per commentary on the amoptions SGML docs.

the same page we are nanoseconds away from reading for real. There should be
something left to do on the current page before we consider issuing a prefetch.

business with inheritance recursion: ALTER INDEX, ALTER SEQUENCE, ALTER
TRIGGER, ALTER VIEW. They would just silently ignore the ONLY.
ALTER TABLE has mixed behavior and cannot be dealt with this way because
of the resulting shift/reduce conflicts.

GUC variable effective_io_concurrency controls how many concurrent block
prefetch requests will be issued.
(The best way to handle this for plain index scans is still under debate,
so that part is not applied yet --- tgl)

we can get some buildfarm feedback about whether that function is still
problematic. (Note that the planned async-preread patch will not really
prove anything one way or the other in buildfarm testing, since it will
be inactive with default GUC settings.)

bitmap. This is extracted from Greg Stark's posix_fadvise patch; it seems
worth committing separately, since it's potentially useful independently of
posix_fadvise.

empty query string is passed to PQexecParams and related functions. Its
handling of the NoData response to Describe messages was subtly incorrect.
Per my report of yesterday.
Although I consider this a bug, it's a behavioral change that might affect
applications, so not back-patched.
In passing fix a second issue in the same code: it didn't react well to an
out-of-memory failure while trying to make the PGresult object.

that are set up for execution with ExecPrepareExpr rather than going through
the full planner process. By introducing an explicit notion of "expression
planning", this patch also lays a bit of groundwork for maybe someday
allowing sub-selects in standalone expressions.

like a makefile with real dependencies.
Instead of overwriting the old po file, write the new one to .po.new. This is
less annoying and integrates better with the NLS web site.
Also, we can now merge languages that don't have a po file yet, by merging
against all other po files of that language, to pick up recurring translations
automatically. This previously only worked when a po file already existed.

In passing, noted that the pg_hba options for krb5 authentication weren't
listed at all - so add this.

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.

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.

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.

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.

Other 8.4 tweaks to the behavior remain in place. Per discussion.
