originally created with, so that the set of visible tuples does not
change as a result of other activity. This essentially makes PG cursors
INSENSITIVE per the SQL92 definition. See bug report of 13-Feb-02.

inline routines do.

compile in client apps that use the standard installed header set.
To allow removing that include, move DLLIMPORT definitions out of c.h
and into the appropriate port-specific header files.

mess up after an aborted VACUUM FULL, per today's pghackers discussion.
Add a suitable HeapTupleSatisfiesToast routine. Remove useless special-
case test in HeapTupleSatisfiesVisibility macro for xmax =
BootstrapTransactionId; perhaps that was needed at one time, but it's
a waste of cycles now, not to mention actively wrong for SnapshotAny.
Along the way, add some much-needed comments to tqual.c, and simplify
toast_fetch_datum, which no longer needs to assume it may see chunks
out-of-order.

to prevent spreading of corruption when page header pointers are bad.
Merge PageZero into PageInit, since it was never used separately, and
remove separate memset calls used at most other PageInit call points.
Remove IndexPageCleanup, which wasn't used at all.

Thanks to Bruce for spotting it and Tom Lane for diagnosing it.
Since horology test output is changing anyway, add some date/time input
tests to horology.sql. Some of these should move to the tests for the
individual data types, and we perhaps should add an entire new test
for "timezone" to allow manipulating the current time zone without
risking damage to the results of other tests.

macros, but only at explicit CHECK_FOR_INTERRUPTS() calls. Not clear
whether overenthusiastic acceptance of interrupts accounts for any real
bugs, but it definitely seems risky and unnecessary.

cases which should have worked but did not.
Now supports julian day (J2452271), ISO time labels (T040506) and various
combinations of spaces and run-togethers of dates, times, and time zones.
All regression tests pass, and I have more tests to add after the 7.2
release (don't want to require changes to the ancillary horology result
files until after then).

object. This should prevent the compiler from reordering loads and stores
into or out of a critical section.

set-returning functions in its target list. This ensures that we
won't rewrite the query in a way that places set-returning functions
into quals (WHERE clauses). Cf. bug reports from Joe Conway.

to use and significantly faster. This tweak saves 25% (!) of the runtime
of COPY IN in a test with 8000-character lines. I wouldn't normally
commit a performance improvement this late in the cycle, but 25% got
my attention...

provide a default definition equating it to 'int'. Should trigger only
on machines with pre-ANSI-C header files, eg SunOS 4.1.x.

Multibyte mode.

This seems the right thing for most usages, but I notice two places
where it is the wrong thing. One is that the default permissions on
TOAST rels should be no-access, not world-readable; the other is that
PrepareForTupleInvalidation doesn't really need to spend time looking
at tuples of TOAST relations.

int8, int16, int32, int64 and separately uint8, uint16, uint32, uint64
The previous patch grouped:
int8, int16 and int32
uint8, uint16 and uint32
int64 and uint64 <-- this grouping is wrong on AIX 4.3.3 and below
If you prefer to make 4 groups out of this you could apply this patch.

the ports that rely on this macro to size data structures are broken.
Mea culpa.

to the target list in gram.y; it must wait till after expansion of the
target list in analyze.c. Per bug report 4-Nov:

CREATE

ERROR: CREATE TABLE/AS SELECT has mismatched column count

so that only one signal number is used not three. Flags in shared
memory tell the reason(s) for the current signal. This method is
extensible to handle more signal reasons without chewing up even more
signal numbers, but the immediate reason is to keep pg_pwd reloads
separate from SIGHUP processing in the postmaster.
Also clean up some problems in the postmaster with delayed response to
checkpoint status changes --- basically, it wouldn't schedule a checkpoint
if it wasn't getting connection requests on a regular basis.

postmaster children before client auth step. Postmaster now rereads
pg_pwd on receipt of SIGHUP, the same way that pg_hba.conf is handled.
No cycles need be expended to validate password cache validity during
connection startup.

recreated since the start of our transaction, our first reference to it
errored out because we'd try to reuse our old relcache entry for it.
Do this by accepting SI inval messages just before relcache search in
heap_openr, so that dead relcache entries will be flushed before we
search. Also, break heap_open/openr into two pairs of routines,
relation_open(r) and heap_open(r). The relation_open routines make
no tests on relkind and so can be used to open anything that has a
pg_class entry. The heap_open routines are wrappers that add a relkind
test to preserve their established behavior. Use the relation_open
routines in several places that had various kluge solutions for opening
rels that might be either heap or index rels.
Also, remove the old 'heap stats' code that's been superseded by Jan's
stats collector, and clean up some inconsistencies in error reporting
between the different types of ALTER TABLE.

from Philip Warner. Side effect of change is that GROUP BY expressions
will not be re-evaluated at multiple plan levels anymore, whereas this
sometimes happened with old code.

per suggestion from Peter. Simplify several APIs by transmitting the
original argv location directly from main.c to ps_status.c, instead of
passing it down through several levels of subroutines.
