from defining non-self-conflicting constraints.

Note: I (tgl) objected to removing this check in 9.0 on the grounds that it
was an important sanity check in new, poorly tested code. However, it should
be all right to remove it for 9.1, since we'll get field testing from the
9.0 branch.

The code was probably meant to be this way all along, since the subroutine
CreateOpFamily previously had only one caller. But it wasn't.

to dump a PUBLIC user mapping correctly, as per bug #5560 from Shigeru Hanada.
Use the pg_user_mappings view rather than trying to access pg_user_mapping
directly, so that the code doesn't fail when run by a non-superuser. And
clean up some minor carelessness such as unsafe usage of fmtId().
Back-patch to 8.4 where this code was added.

parameter against server cert's CN field) to succeed in the case where
both host and hostaddr are specified. As with the existing precedents
for Kerberos, GSSAPI, SSPI, it is the calling application's responsibility
that host and hostaddr match up --- we just use the host name as given.
Per bug #5559 from Christopher Head.
In passing, make the error handling and messages for the no-host-name-given
failure more consistent among these four cases, and correct a lie in the
documentation: we don't attempt to reverse-lookup host from hostaddr
if host is missing.
Back-patch to 8.4 where SSL cert verification was introduced.

rather than just $N. This brings the display of nestloop-inner-indexscan
plans back to where it's been, and incidentally improves the display of
SubPlan parameters as well. In passing, simplify the EXPLAIN code by
having it deal primarily in the PlanState tree rather than separately
searching Plan and PlanState trees. This is noticeably cleaner for
subplans, and about a wash elsewhere.
One small difference from previous behavior is that EXPLAIN will no longer
qualify local variable references in inner-indexscan plan nodes, since it
no longer sees such nodes as possibly referencing multiple tables. Vars
referenced through PARAM_EXEC Params are still forcibly qualified, though,
so I don't think the display is any more confusing than before. Adjust a
couple of examples in the documentation to match this behavior.

loop from being dropped, I missed subtransaction cleanup. Pinned portals
must be dropped at subtransaction cleanup just as they are at main
transaction cleanup.
Per bug #5556 by Robert Walker. Backpatch to 8.0, 7.4 didn't have
subtransactions.

relation using the general PARAM_EXEC executor parameter mechanism, rather
than the ad-hoc kluge of passing the outer tuple down through ExecReScan.
The previous method was hard to understand and could never be extended to
handle parameters coming from multiple join levels. This patch doesn't
change the set of possible plans nor have any significant performance effect,
but it's necessary infrastructure for future generalization of the concept
of an inner indexscan plan.
ExecReScan's second parameter is now unused, so it's removed.

use the actual element type of the array it's disassembling, rather than
trusting the type OID passed in by its caller. This is needed because
sometimes the planner passes in a type OID that's only binary-compatible
with the target column's type, rather than being an exact match. Per an
example from Bernd Helmle.
Possibly we should refactor get_attstatsslot/free_attstatsslot to not expect
the caller to supply type ID data at all, but for now I'll just do the
minimum-change fix.
Back-patch to 7.4. Bernd's test case only crashes back to 8.0, but since
these subroutines are the same in 7.4, I suspect there may be variant
cases that would crash 7.4 as well.

resjunk outputs of subquery tlists, instead of throwing an error. Per bug
#5548 from Daniel Grace.
We might at some point find we ought to back-patch this further than 9.0,
but I think that such Vars can only occur as resjunk members of upper-level
tlists, in which case the problem can't arise because prior versions didn't
print resjunk tlist items in EXPLAIN VERBOSE.

This hook allows a loadable module to gain control when table permissions
are checked. It is expected to be used by an eventual SE-PostgreSQL
implementation, but there are other possible applications as well. A
sample contrib module can be found in the archives at:

(_PG_init should be called only once anyway, but as long as it's got an
internal guard against repeat calls, that should be in front of the
version check.)

SIO_KEEPALIVE_VALS define instead of just WIN32, since MingW doesn't
support this API (yet?).

This wasn't important when we used diff's -w (--ignore-all-space) option
to compare regression result files, but it is now. Per buildfarm member

but came to life again today.

sub-select contains a join alias reference that expands into an expression
containing another sub-select. Per yesterday's report from Merlin Moncure
and subsequent off-list investigation.
Back-patch to 7.4. Older versions didn't attempt to flatten sub-selects in
ways that would trigger this problem.
|
|
To do that, replace L'\0' by (WCHAR) 0. Perhaps someday we should teach
pgindent about wide-character literals, but so long as this is the only
use-case in the entire Postgres sources, a workaround seems easier.
|
|
Per extensive discussion on pgsql-hackers. We are deliberately not
back-patching this even though the behavior of 8.3 and 8.4 is
unquestionably broken, for fear of breaking existing users of this
parameter. This incompatibility should be release-noted.

flag for src/port/ in front of any -L flags placed in LDFLAGS by configure.
This undoes an L-flag-ordering change that I had thought would be safe,
but seems to be making at least one buildfarm member fail --- the only
theory for orca's failure that I can think of is that it's got an old
copy of libpgport.a in /usr/lib. Also allow for LDFLAGS_SL to be set by
contrib makefiles before they invoke Makefile.global.

MacOS X uses TCP_KEEPALIVE rather than TCP_KEEPIDLE for this purpose.
Thanks to Fujii Masao for the review.

needs to appear before anything placed in SHLIB_LINK. This is because
SHLIB_LINK is typically a subset of LIBS, and LIBS has to appear after
LDFLAGS on platforms that are sensitive to the relative order of -L and -l
switches.

Per buildfarm results.

stay in front of LDFLAGS.
|

Solaris, at least, seems to be sensitive to the relative order of -L
and -l switches, so this is needed. Per buildfarm results.

supposing that they should set SHLIB_LINK rather than LDFLAGS_SL. Since these
don't go through Makefile.shlib that was a no-op on most platforms. Also
regularize the few platform-specific Makefiles that did pay attention to
SHLIB_LINK: it seems that the real value of that is to pull in BE_DLLLIBS,
so do that instead. Per buildfarm failures on cygwin.

linking both executables and shared libraries, and we add on LDFLAGS_EX when
linking executables or LDFLAGS_SL when linking shared libraries. This
provides a significantly cleaner way of dealing with link-time switches than
the former behavior. Also, make sure that the various platform-specific
%.so: %.o rules incorporate LDFLAGS and LDFLAGS_SL; most of them missed that
before. (I did not add these variables for the platforms that invoke $(LD)
directly, however. It's not clear if we can do that safely, since for the
most part we assume these variables use CC command-line syntax.)
Per gripe from Aaron Swenson and subsequent investigation.

being used in a PL/pgSQL FOR loop is closed was inadequate, as Tom Lane
pointed out. The bug affects FOR statement variants too, because you can
close an implicitly created cursor too by guessing the "<unnamed portal X>"
name created for it.
To fix that, "pin" the portal to prevent it from being dropped while it's
being used in a PL/pgSQL FOR loop. Backpatch all the way to 7.4 which is
the oldest supported version.

idea from the start since the variable is only meant to track commit/abort
events. This patch reverts the logic around the variable to what it was in
8.4, except that the value is now kept in shared memory rather than a static
variable, so that it can be reported correctly by CreateRestartPoint (which is
executed in the bgwriter).

to have different values in different processes of the primary server.
Also put it into the "Streaming Replication" GUC category; it doesn't belong
in "Standby Servers" because you use it on the master not the standby.
In passing also correct guc.c's idea of wal_keep_segments' category.

max_standby_streaming_delay, and revise the implementation to avoid assuming
that timestamps found in WAL records can meaningfully be compared to clock
time on the standby server. Instead, the delay limits are compared to the
elapsed time since we last obtained a new WAL segment from archive or since
we were last "caught up" to WAL data arriving via streaming replication.
This avoids problems with clock skew between primary and standby, as well
as other corner cases that the original coding would misbehave in, such
as the primary server having significant idle time between transactions.
Per my complaint some time ago and considerable ensuing discussion.
Do some desultory editing on the hot standby documentation, too.

Backpatch to 8.3, which is as far back as we have opfamilies.
The opclass portion could probably be backpatched to 8.2, when
REASSIGN OWNED was added, but for now I have not done that.
Asko Tiidumaa, with minor adjustments by me.

The previous commit to make copydir() interruptible prevented
postgres.exe from linking on MinGW and Cygwin, because on those
platforms libpgport_srv.a can't freely reference symbols defined
by the backend. Since that code is already backend-specific anyway,
just move the whole file into the backend rather than adding further
kludges to deal with the symbols needed by CHECK_FOR_INTERRUPTS().
This probably needs some further cleanup, but this commit just moves
the file as-is, which should hopefully be enough to turn the
buildfarm green again.

This makes ALTER DATABASE .. SET TABLESPACE and CREATE DATABASE more
sensitive to interrupts. Backpatch to 8.4, where ALTER DATABASE .. SET
TABLESPACE was introduced. We could go back further, but in the absence
of complaints about the CREATE DATABASE case it doesn't seem worth it.
Guillaume Lelarge, with a small correction by me.

Backpatch to 8.0, where tablespaces were introduced.
