5ce63f480b Avoid an Assert failure in deconstruct_array() by making get_attstatsslot()
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.

2b8a624596 Fix ruleutils' get_variable() to print something useful for Vars referencing
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.

f4122a8d50 Add a hook in ExecCheckRTPerms().
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:

6d297e0551 Minor kibitzing on previous patch: no need to run check more than once.
(_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.)

d4d32eefdf Fix "cannot handle unplanned sub-select" error that can occur when a
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.

5b1b3ef742 Adjust mbutils.c so it won't get broken by future pgindent runs.
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.

20be0d480a Make log_temp_files based on kB, and revert docs & comments to match.
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.

458474d9d7 Accept slightly grotty coding in Makefile.global in order to keep the -L
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.

8307b092b7 Still more third thoughts: when linking shared libraries, LDFLAGS probably
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.

f6af1435d9 Dept. of third thoughts: PG_LIBS may contain a -L switch, so it had better

bdf00543c2 Make sure LDFLAGS come before LIBS when linking contrib programs.
Solaris, at least, seems to be sensitive to the relative order of -L
and -l switches, so this is needed.  Per buildfarm results.

f9e9da6664 Fix a few single-file (MODULES, not MODULE_big) contrib makefiles that were
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.

291a957745 Split the LDFLAGS make variable into two parts: LDFLAGS is now used for
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.

eb81b6509f The previous fix in CVS HEAD and 8.4 for handling the case where a cursor
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.

8771634666 Don't set recoveryLastXTime when replaying a checkpoint --- that was a bogus
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).

aceedd88f6 Make vacuum_defer_cleanup_age be PGC_SIGHUP level, since it's not sensible
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.
2010-07-03 21:23:58 +00:00
Tom Lane
e76c1a0f4d Replace max_standby_delay with two parameters, max_standby_archive_delay and
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.

REASSIGN OWNED was added, but for now I have not done that.
