Declaring this in the client-visible header ecpglib.h was a pretty
poor decision. It's not meant to be application-callable (and if
it was, putting it outside the extern "C" { ... } wrapper means
that C++ clients would fail to call it). And the declaration would
not even compile for a client, anyway, since it would not have the
macro pg_attribute_format_arg(). Fortunately, it seems that no
clients have tried to include this header with ENABLE_NLS defined,
or we'd have gotten complaints about that. But we have no business
putting such a restriction on client code.
Move the declaration to ecpglib_extern.h, since in fact nothing
outside src/interfaces/ecpg/ecpglib/ needs to call it.
The practical effect of this is just that clients can now safely
#include ecpglib.h while having ENABLE_NLS defined, but that seems
like enough of a reason to back-patch it.

This patch adopts the overflow check logic introduced by commit cbdb8b4c0
into two more places. interval_mul() failed to notice if it computed a
new microseconds value that was one more than INT64_MAX, and pgbench's
double-to-int64 logic had the same sorts of edge-case problems that
cbdb8b4c0 fixed in the core code.

into new macros in c.h, and add commentary about how to use the macros
correctly.

When sending data for logical decoding using the streaming replication
protocol via a WAL sender, the timestamp of the sent write message is
allocated at the beginning of the message when preparing for the write,
and actually computed when the write message is ready to be sent.
The timestamp was getting computed after sending the message. This
impacts anything using logical decoding, causing for example logical

WindowAgg will potentially store large numbers of input rows into
tuplestores to allow access to other rows in the frame. If the input
is coming via an explicit Sort node, then unneeded columns will
already have been discarded (since Sort requests a small tlist); but
there are idioms like COUNT(*) OVER () that result in the input not
being sorted at all, and cases where the input is being sorted by some
means other than a Sort; if we don't request a small tlist, then
WindowAgg's storage requirement is inflated by the unneeded columns.

For a long time (since commit aed378e8d) we have had a policy to log
nothing about a connection if the client disconnects when challenged
for a password. This is because libpq-using clients will typically
do that, and then come back for a new connection attempt once they've
collected a password from their user, so that logging the abandoned
connection attempt will just result in log spam. However, this did
not work well for PAM authentication: the bottom-level function
pam_passwd_conv_proc() was on board with it, but we logged messages
at higher levels anyway, for lack of any reporting mechanism.

Backpatch: 9.5, like 2c03216d831.
This is a back-patch of the v10 commit d8c05aff5. The motivation for
doing this now is that we received a complaint that a view with a
circular dependency is dumped with an extra bogus command "ALTER TABLE
ONLY myview REPLICA IDENTITY NOTHING", because pg_dump forgets that it's
a view not a table, and the relreplident value stored for a view is that.
So you'll get an error message during restore even if not using --clean;
this would break pg_upgrade for example. While that could be handled
with a one-line patch, it seems better to back-patch d8c05aff5, since that
produces cleaner more future-proof output and fixes an additional bug.
Per gripe from Alex Williams. Back-patch to 9.4-9.6 (even if 9.3 were

Original commit message follows:
pg_dump's traditional solution for breaking a circular dependency involving
a view was to create the view with CREATE TABLE and then later issue CREATE
RULE "_RETURN" ... to convert the table to a view, relying on the backend's
very very ancient code that supports making views that way. We've wanted
to get rid of that kluge for a long time, but the thing that finally
motivates doing something about it is the recognition that this method
fails with the --clean option, because it leads to issuing DROP RULE
"_RETURN" followed by DROP TABLE --- and the backend won't let you drop a
view's _RETURN rule.
Instead, let's break circular dependencies by initially creating the view
using CREATE VIEW AS SELECT NULL::columntype AS columnname, ... (so that
it has the right column names and types to support external references,
but no dependencies beyond the column data types), and then later dumping
the ON SELECT rule using the spelling CREATE OR REPLACE VIEW. This method
wasn't available when this code was originally written, but it's been
possible since PG 7.3, so it seems fine to start relying on it now.
To solve the --clean problem, make the dropStmt for an ON SELECT rule
be CREATE OR REPLACE VIEW with the same dummy target list as above.
In this way, during the DROP phase, we first reduce the view to have
no extra dependencies, and then we can drop it entirely when we've
gotten rid of whatever had a circular dependency on it.
(Note: this should work adequately well with the --if-exists option, since
the CREATE OR REPLACE VIEW will go through whether the view exists or not.
It could fail if the view exists with a conflicting column set, but we
don't really support --clean against a non-matching database anyway.)
This allows cleaning up some other kluges inside pg_dump, notably that
we don't need a notion of reloptions attached to a rule anymore.
Although this is a bug fix, commit to HEAD only for now. The problem's
existed for a long time and we've had relatively few complaints, so it
doesn't really seem worth taking risks to fix it in the back branches.
We might revisit that choice if no problems emerge.

Move the platform-dependent logic that sets CFLAGS_SL from

is determined at configure time and thus is available while running
configure's tests.
On a couple of platforms this might save a few microseconds of build
time by eliminating a test that make otherwise has to do over and over.
Otherwise it's pretty much a wash for build purposes; in particular,
this makes no difference to anyone who might be overriding CFLAGS_SL
via a make option.
This patch in itself does nothing with the value and thus should not
change any behavior, though you'll probably have to re-run configure
to get a correctly updated Makefile.global. We'll use the new

recovery_min_apply_delay parameter is intended for use with streaming
replication deployments. However, the document clearly explains that
the parameter will be honored in all cases if it's specified. So it should
take effect even if in archive recovery. But, previously, archive recovery
with recovery_min_apply_delay enabled always failed, and caused assertion
failure if --enable-caasert is enabled.
The cause of this problem is that; the ownership of recoveryWakeupLatch
that recovery_min_apply_delay uses was taken only when standby mode
is requested. So unowned latch could be used in archive recovery, and
which caused the failure.
This commit changes recovery code so that the ownership of
recoveryWakeupLatch is taken even in archive recovery. Which prevents
archive recovery with recovery_min_apply_delay from failing.

The pg_upgrade check for pg_catalog.line data type when upgrading from
9.3 had a couple of issues with domains and composite types. Firstly, it
triggered false positives for composite types unused in objects with
storage. This was enough to trigger an unnecessary pg_upgrade failure:
CREATE TYPE line_composite AS (l pg_catalog.line)
On the other hand, this only happened with composite types directly on
the pg_catalog.line data type, but not with a domain. So this was not
detected
CREATE DOMAIN line_domain AS pg_catalog.line;
CREATE TYPE line_composite_2 AS (l line_domain);
unlike the first example. These false positives and inconsistencies are
unfortunate, but what's worse we've failed to detected objects using the
pg_catalog.line data type through a domain. So we missed cases like this
CREATE TABLE t (l line_composite_2);
The consequence is clusters broken after a pg_upgrade.
This fixes these false positives and false negatives by using the same
recursive CTE introduced by eaf900e842 for sql_identifier. 9.3 did not

Encoding conversion uses the very simplistic rule that the output
can't be more than 4X longer than the input, and palloc's a buffer
of that size. This results in failure to convert any string longer
than 1/4 GB, which is becoming an annoying limitation.
As a band-aid to improve matters, allow the allocated output buffer
size to exceed 1GB. We still insist that the final result fit into
MaxAllocSize (1GB), though. Perhaps it'd be safe to relax that
restriction, but it'd require close analysis of all callers, which
is daunting (not least because external modules might call these
functions). For the moment, this should allow a 2X to 4X improvement
in the longest string we can convert, which is a useful gain in
return for quite a simple patch.
Also, once we have successfully converted a long string, repalloc
the output down to the actual string length, returning the excess
to the malloc pool. This seems worth doing since we can usually
expect to give back several MB if we take this path at all.
This still leaves much to be desired, most notably that the assumption
that MAX_CONVERSION_GROWTH == 4 is very fragile, and yet we have no
guard code verifying that the output buffer isn't overrun. Fixing
that would require significant changes in the encoding conversion
APIs, so it'll have to wait for some other day.
The present patch seems safely back-patchable, so patch all supported

That's unpleasant if a really large allocation is resized to a

code was designed, and I'm not sure whether they're common even yet,
but an upcoming fix to encoding conversion will certainly create such

The test name and the following test cases suggest the index created
should be hash index, but it forgot to add 'using hash' in the test case.
This in itself won't improve code coverage as there were some other tests
which were covering the corresponding code. However, it is better if the
added tests serve their actual purpose.
