Here's an attempt on this. new file goes in backend/port/win32.

some possible causes of the stale postmaster.pid problem that some users
have reported.
- The service did not properly report that it accepts
SERVICE_CONTROL_SHUTDOWN events, thus it's possible the SCM simply
killed the postmaster on shutdown.
- 'WaitHints' are now given to the SCM to prevent it timing out if
pg_ctl doesn't respond to a control event quickly enough.
- During shutdown, the service checkpoint counter is incremented every
five seconds for up to a minute to prevent the SCM timing out and
assuming the service is not responding.

Please find attached a small patch against current CVS head that fixes
pgport library installation so that it goes to libdir instead of
pkglibdir. It works for me.

so that we close and flush the doomed relation's relcache entry before
we start to delete the underlying catalog rows, rather than afterwards.
For awhile yesterday I thought that an unexpected relcache entry rebuild
partway through this sequence might explain the infrequent parallel
regression failures we were chasing. It doesn't, mainly because there's
no CommandCounterIncrement in the sequence and so the deletions aren't
"really" done yet. But it sure seems like trouble waiting to happen.

relcache entries. Also, change TransactionIdIsCurrentTransactionId()
so that if consulted during transaction abort, it will not say that
the aborted xact is still current. (It would be better to ensure that
it's never called at all during abort, but I'm not sure we can easily
guarantee that.) In combination, these fix a crash we have seen
occasionally during parallel regression tests of 8.0.

Also add regression test cases for this change, and for previous
recent array literal parser changes.

is actually better than the Unix behavior. Per Dave Page and Andrew Dunstan.

PROCLOCK structs in shared memory now have only a bitmask for held
locks, rather than counts (making them 40 bytes smaller, which is a
good thing). Multiple locks within a transaction are counted in the
local hash table instead, and we have provision for tracking which
ResourceOwner each count belongs to. Solves recently reported problem
with memory leakage within long transactions.

for every command executed within a transaction. For long transactions
this was a significant memory leak. Instead, we can delete a portal's
or subtransaction's ResourceOwner immediately, if we physically transfer
the information about its locks up to the parent owner. This does not
fully solve the leak problem; we need to do something about counting
multiple acquisitions of the same lock in order to fix it. But it's a
necessary step along the way.

ColLabel instead of just ColId --- that is, any keyword can appear after
a dot and it will be taken as an identifier. Fixes problems with names
that are okay as standalone function names but fail when qualified.

SGML markup, add a "deprecated features" section to the 8.0 release
notes, untabify release.sgml and runtime.sgml, and make some other
minor improvements.

updates are no longer WAL-logged nor even fsync'd; we do not need to,
since after a crash no old pg_subtrans data is needed again. We truncate
pg_subtrans to RecentGlobalXmin at each checkpoint. slru.c's API is
refactored a little bit to separate out the necessary decisions.

RecentXmin (== MyProc->xmin). This ensures that it will be safe to
truncate pg_subtrans at RecentGlobalXmin, which should largely eliminate
any fear of bloat. Along the way, eliminate SubTransXidsHaveCommonAncestor,
which isn't really needed and could not give a trustworthy result anyway
under the lookback restriction.
In an unrelated but nearby change, #ifdef out GetUndoRecPtr, which has
been dead code since 2001 and seems unlikely to ever be resurrected.
