c64339face When updating ShmemVariableCache from a checkpoint record, be sure to set
all the values derived from oldestXid, not just that field.  Brain fade in
one of my patches associated with flat file removal, exposed by a report
from Fujii Masao.

With this change, xidVacLimit should always be valid, so remove a couple of
bits of complexity associated with the previous assumption that sometimes
it wouldn't get set right away.

ee678fe30c Make NOTIFY_PAYLOAD_MAX_LENGTH depend explicitly on BLCKSZ and
NAMEDATALEN, so this code doesn't go nuts with smaller than default
BLCKSZ or larger than default NAMEDATALEN.  The standard value is
still exactly 8000.

d1e027221d Replace the pg_listener-based LISTEN/NOTIFY mechanism with an in-memory queue.
In addition, add support for a "payload" string to be passed along with
each notify event.

This implementation should be significantly more efficient than the old one,
and is also more compatible with Hot Standby usage.  There is not yet any
facility for HS slaves to receive notifications generated on the master,
although such a thing is possible in future.

56adf3703c Clean up package namespace use and use of Safe in plperl.
Prevent use of another buggy version of Safe.pm.
Only register the exit handler if we have  successfully created an interpreter.
Change log level of perl warnings from NOTICE to WARNING.

The infrastructure is there if in future we decide to allow
DBAs to specify extra modules that will be allowed in trusted code.
However, for now the relevant variables are declared as lexicals
rather than as package variables, so that they are not (or should not be)
accessible.

Mostly code from Tim Bunce, reviewed by Alex Hunsaker, with some
tweaks by me.

215cbc90f8 Add emulation of non-blocking sockets to the win32 socket/signal layer,
and use this in pq_getbyte_if_available.

It's only a limited implementation which swithes the whole emulation layer
no non-blocking mode, but that's enough as long as non-blocking is only
used during a short period of time, and only one socket is accessed during
this time.

4a5ee2a419 Move main error message text in plperl into errmsg from errdetail,
and move the context information into errcontext instead of errmsg.
This makes them better conform to our guidelines.

Also remove a few errcode declarations that were providing the default
value ERRCODE_INTERNAL_ERROR.

f8c183a1ac Speed up CREATE DATABASE by deferring the fsyncs until after copying
all the data and using posix_fadvise to nudge the OS into flushing it
earlier. This also hopefully makes CREATE DATABASE avoid spamming the
cache.

Tests show a big speedup on Linux at least on some filesystems.

Idea and patch from Andres Freund.

e26c539e9f Wrap calls to SearchSysCache and related functions using macros.
The purpose of this change is to eliminate the need for every caller
of SearchSysCache, SearchSysCacheCopy, SearchSysCacheExists,
GetSysCacheOid, and SearchSysCacheList to know the maximum number
of allowable keys for a syscache entry (currently 4).  This will
make it far easier to increase the maximum number of keys in a
future release should we choose to do so, and it makes the code
shorter, too.

Design and review by Tom Lane.

1012492bc0 Make CREATE DATABASE safe against losing whole files by fsyncing the
directory and not just the individual files.

fsynced anything anyways.

a05af1d404 Make the msvc build system ask python about details of version and installation
prefix, instead of assuming it will always be following the default layout.

All information we need is not available on Windows, but the number of
assumptions are at least fewer this way than before.

Based on suggestions from James William Pye.

7507b193bc Don't expose the inline definition of MemoryContextSwitchTo when FRONTEND is
defined.  Its reference to CurrentMemoryContext causes link failures on some
platforms, evidently because the inline function gets compiled despite lack of

e08ab7c312 Support inlining various small performance-critical functions on non-GCC
compilers, by applying a configure check to see if the compiler will accept
an unreferenced "static inline foo ..." function without warnings.  It is
believed that such warnings are the only reason not to declare inlined
functions in headers, if the compiler understands "inline" at all.

b95a720a48 Re-enable max_standby_delay = -1 using deadlock detection on startup
process. If startup waits on a buffer pin we send a request to all
backends to cancel themselves if they are holding the buffer pin
required and they are also waiting on a lock. If not, startup waits
until max_standby_delay before cancelling any backend waiting for
the requested buffer pin.

4688869f41 Tweak the order of processing of WITH clauses so that they are processed
before we start analyzing the parent statement.  This is to make it
more clear that the WITH isn't affected by anything in the parent.
I don't believe there's any actual bug here, because the stuff that
was being done before WITH didn't affect subqueries; but it's certainly
a potential for error (and apparently misled Marko into committing some
real errors...).

3ad7dbb1b9 Don't choke when exec_move_row assigns a synthesized null to a column

composite-type support to make this worth worrying about in that branch.

ec4be2ee68 Extend the set of frame options supported for window functions.
This patch allows the frame to start from CURRENT ROW (in either RANGE or
ROWS mode), and it also adds support for ROWS n PRECEDING and ROWS n FOLLOWING
start and end points.  (RANGE value PRECEDING/FOLLOWING isn't there yet ---
the grammar works, but that's all.)

e465390d03 Reduce the chatter to the log when starting a standby server. Don't
echo all the recovery.conf options. Don't emit the "initializing
recovery connections" message, which doesn't mean anything to a user.
Remove the "starting archive recovery" message and replace the
"automatic recovery in progress" message with a more informative message
saying whether the server is doing PITR, normal archive recovery, or
standby mode.

9fa01f6c8a Check for partial WAL files in standby mode. If restore_command restores
a partial WAL file, assume it's because the file is just being copied to
the archive and treat it the same as "file not found" in standby mode.
pg_standby has a similar check, so it seems reasonable to have the same
level of protection in the built-in standby mode.
