In PLy_spi_execute_plan, use the data-type specific Python-to-PostgreSQL
conversion function instead of passing everything through InputFunctionCall
as a string. The equivalent fix was already done months ago for function
parameters and return values, but this other gateway between Python and
PostgreSQL was apparently forgotten. As a result, data types that need
special treatment, such as bytea, would misbehave when used with
plpy.execute.
in recovery_end_command, it always came out as 0 because InRedo was
cleared before recovery_end_command was executed. Also, always take
ControlFileLock when reading checkpoint location for %r.
The recovery_end_command bug and the missing locking was present in 8.4
as well, that part of this patch will be backported separately.
This variable is apparently only for Python internally. In newer releases
of Python this variable pulls in more and more libraries that users are
less likely to have, leading to potential build failures.
to transformAggregateCall, instead of abusing fields in Aggref to carry them
temporarily. No change in functionality but hopefully the code is a bit
clearer now. Per gripe from Gokulakannan Somasundaram.
unable to read a stats file for reasons other than ENOENT, and having to reset
last_statrequest because it's later than current time in the collector.
Not clear if this will shed any light on the "pgstat wait timeout" business,
but it seems like a good idea in general.
In passing, do some message-style-police work on recently-added
pgstat_reset_shared_counters code.
corner cases that come up in certain timezones (apparently, only those with
lots and lots of distinct TZ transition rules, as far as I can gather from
a quick scan of their archives). Per suggestion from Jeevan Chalke.
Back-patch to 8.4. Possibly we need to push this into earlier releases
as well, but I'm hesitant to update them to the 64-bit tzcode without
more thought and testing.
by joining to pg_constraint.conindid, instead of the former technique of
joining indirectly through pg_depend. This is much more straightforward
and probably faster as well. I had originally desisted from changing these
queries when conindid was added because I was worried about losing
performance, but if we join on conrelid as well as conindid then the index
on conrelid can be used when pg_constraint is large.
instead of an exclusive lock.
The change is almost for code cleanup. Since there seems to be no
performance benefits from it, backports should not be needed.

The latter is considered unwarranted chumminess with the implementation,
and can lead to crashes with recent Perl versions.
Report and fix by Tim Bunce. Back-patch to all versions containing the
questionable coding pattern.
--single-transaction are both used and the failure happens in commit,
e.g. failed deferred trigger. Also properly free BEGIN/COMMIT result
structures from --single-transaction.
