Make btree index creation and initial validation of foreign-key constraints
use maintenance_work_mem rather than work_mem as their memory limit.
Add some code to guc.c to allow these variables to be referenced by their
old names in SHOW and SET commands, for backwards compatibility.

whereToSendOutput instead because they are really inquiring about
the correct client communication protocol. Update some comments.
This is pointing towards supporting regular FE/BE client protocol
in a standalone backend, per discussion a month or so back.

PostmasterPid variable, which gets set (early) in PostmasterMain
getppid would not be the postmaster?
[fork/exec] Implements processCancelRequest by keeping an array of
pid/cancel_key structs in shared mem
[fork/exec] Moves AttachSharedMemoryAndSemaphores call for backends into
SubPostmasterMain
[win32] Implements reaper/waitpid by keeping an arrays of children
pids,handles in postmaster local mem
- this item is largely untested, for reasons which should be
obvious, but appears sound
[win32/all] Added extern for pgpipe in Win32 case, and changed the second
pipe call (which seems to have been missed earlier) to pgpipe
[win32] #define'd ftruncate to chsize in the Win32 case
[win32] PG_USLEEP for Win32 has a misplaced paren. Fixed.
[win32] DLLIMPORT handling for MingW case

on 64-bit Solaris. Use a non-system-dependent datatype for UsedShmemSegID,
namely unsigned long (which we were already assuming could hold a shmem
key anyway, cf RecordSharedMemoryInLockFile).

protocol, per report from Igor Shevchenko. NOTIFY thought it could
do its thing if transaction blockState is TBLOCK_DEFAULT, but in
reality it had better check the low-level transaction state is
TRANS_DEFAULT as well. Formerly it was not possible to wait for the
client in a state where the first is true and the second is not ...
but now we can have such a state. Minor cleanup in StartTransaction()
as well.

the help message generated by --help-config -h be more similar in style to
the others.

now able to cope with assigning new relfilenode values to nailed-in-cache
indexes, so they can be reindexed using the fully crash-safe method. This
leaves only shared system indexes as special cases. Remove the 'index
deactivation' code, since it provides no useful protection in the shared-
index case. Require reindexing of shared indexes to be done in standalone
mode, but remove other restrictions on REINDEX. -P (IgnoreSystemIndexes)
now prevents using indexes for lookups, but does not disable index updates.
It is therefore safe to allow from PGOPTIONS. Upshot: reindexing system catalogs
can be done without a standalone backend for all cases except
shared catalogs.

not before, to avoid duplication of effort.

config file if it exists. This was already discussed as being a good
idea, and now seems the cleanest way to deal with initdb-time failures
on machines with small SHMMAX. (The submitted patches instead modified
initdb.sh to pass the correct sizing parameters, but that would still
leave standalone backends prone to failure later. An admin who needs
to use a standalone backend has enough trouble already, he shouldn't
have to manually configure its shmem settings...)

max_connections at initdb time. Get rid of DEF_NBUFFERS and DEF_MAXBACKENDS
macros, which aren't doing anything useful anymore, and put more likely
defaults into postgresql.conf.sample.

just before CommitTransactionCommand(). This is a more sensible place
to put it since commit discards a lot of contexts, and we'd not find
out about stomps affecting only transaction-local contexts.

heuristic determination of day vs month in date/time input. Add the
ability to specify that input is interpreted as yy-mm-dd order (which
formerly worked, but only for yy greater than 31). DateStyle's input
component now has the preferred spellings DMY, MDY, or YMD; the older
keywords European and US are now aliases for the first two of these.
Per recent discussions on pgsql-general.

Along the way, fix some logic problems in pgstat_initstats, notably the

This fixes problems caused by making certain variables SUSET for

without needing a running backend. Reorder postgresql.conf.sample

handle multiple 'formats' for data I/O. Restructure CommandDest and
DestReceiver stuff one more time (it's finally starting to look a bit
clean though). Code now matches latest 3.0 protocol document as far
as message formats go --- but there is no support for binary I/O yet.
