the individual privilege bits. I regard this as an important change for
cross-version compatibility: without this, a 7.1 dump loaded into 7.2
is likely to be short a few privileges.
removes any empty chunks, the chunk previously added won't be there
anymore, so it's possible there is zero free space in the rel's page list
afterwards. Must loop back and rerun the part that adds a chunk to
the list.
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.
This saves one open file descriptor per backend, and avoids an
annoying NOTICE on Cygwin (which has trouble deleting open files).
Bug appears to date back to original coding of init_irels, circa 1992.
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.
per my proposal of a couple days ago. This will eliminate the unable-
to-restart-database class of problem that we have seen reported half a
dozen times with 7.1.*.
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.
their names from pg_class. This considerably reduces the window wherein
someone could DROP or ALTER a table that pg_dump is intending to dump.
Not a perfect solution, but definitely an improvement. Per complaints
from Marc Fournier; patch by Brent Verner with some kibitzing by Tom Lane.
