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.
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.

formats for geometric types. Per bug #5536 from Jon Strait, and my own
testing.
Back-patch to all supported branches, since this doco has been wrong right
along -- we certainly haven't changed the I/O behavior of these types in
many years.
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.

but we have nevertheless exposed them to users via pg_get_expr(). It would
be too much maintenance effort to rigorously check the input, so put a hack
in place instead to restrict pg_get_expr() so that the argument must come
from one of the system catalog columns known to contain valid expressions.
Per report from Rushabh Lathia. Backpatch to 7.4 which is the oldest
supported version at the moment.
as well as fseeko, and to not assume that fseeko(fp, 0, SEEK_CUR) proves
anything. Also improve some related comments. Per my observation that
the SEEK_CUR test didn't actually work on some platforms, and subsequent
discussion with Robert Haas.
Back-patch to 8.4. In earlier releases it's not that important whether
we get the hasSeek test right, but with parallel restore it matters.
contain data offsets (which it won't, if pg_dump thought its output wasn't
seekable). To do that, remove an unnecessarily aggressive error check, and
instead fail if we get to the end of the archive without finding the desired
data item. Also improve the error message to be more specific about the
cause of the problem. Per discussion of recent report from Igor Neyman.
Back-patch to 8.4 where parallel restore was introduced.
The revised documentation makes it more clear that these are client-side
parameters, rather than server side parameters. It also puts the main
point of each parameter first, and consolidates the conditions under which
it might be ignored in a single list at the end.
of YYSTYPE, and hence returning the wrong answer for cases where a plpgsql
"unreserved keyword" really does conflict with a variable name. Obviously
I didn't test this enough :-(. Per bug #5524 from Peter Gagarinov.
