directory/symlink before creation.
Report from Tom Lane.
Backpatch to 9.0.
|
|
Per discussion with David Christensen, there can be multiple
instances of PG accessible via local sockets, and you need the port
to see which one you're actually connected to. David's original
patch worked this way, but I inadvertently ripped it out during
commit.

Per buildfarm, again.

Normally, we automatically restart after a backend crash, but in some
cases when PostgreSQL is invoked by clusterware it may be desirable to
suppress this behavior, so we provide an option which does this.
Since no existing GUC group quite fits, create a new group called
"error handling options" for this and the previously undocumented GUC
exit_on_error, which is now documented.

This change should be publicized to driver maintainers at once and
release-noted as an incompatibility with previous releases.

path when CSV logging is configured but not yet operational. It's sufficient
to send the message to stderr, as we were already doing, and the "Not safe"
gripe has already confused at least two core members ...
Backpatch to 9.0, but not further --- doesn't seem appropriate to change
this behavior in stable branches.

any implicit casting previously applied to the targetlist item. This is
reasonable because the implicit cast, by definition, wasn't written by the
user; so we are preserving the expected behavior that ORDER BY items match
textually equivalent tlist items. The case never arose before because there
couldn't be any implicit casting of a top-level SELECT item before we process
ORDER BY etc. But now it can arise in the context of aggregates containing
ORDER BY clauses, since the "targetlist" is the already-casted list of
arguments for the aggregate. The net effect is that the datatype used for
ORDER BY/DISTINCT purposes is the aggregate's declared input type, not that
of the original input column; which is a bit debatable but not horrendous,
and to do otherwise would require major rework that doesn't seem justified.
Per bug #5564 from Daniel Grace. Back-patch to 9.0 where aggregate ORDER BY
was implemented.

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

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.)

This wasn't important when we used diff's -w (--ignore-all-space) option

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.

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.
