explicitly. This means a TOAST pointer takes 18 bytes instead of 17 --- still
smaller than in 8.2 --- which seems a good tradeoff to ensure we won't have
painted ourselves into a corner if we want to support multiple types of TOAST
pointer later on. Per discussion with Greg Stark.
while the restore_command does its thing, then 'recovering XXX' while
processing the segment file. These operations are heavyweight enough
that an extra PS display set shouldn't bother anyone.
testing). Combine the formerly independent opclasses for the various
ISN types into opfamilies. The latter causes some extra bleating from
opr_sanity, since the module doesn't provide complete sets of cross-type
operators, but it's still a good idea because it will give the planner
more information to work with. The missing cross-type operators no longer
pose a risk of unexpected planner errors in 8.3, so there's no need to
insist on filling them in (and I gather it wouldn't be very sound
semantically to add them all).
CREATE INDEX CONCURRENTLY). Such an index might not have entries for every
heap row and thus clustering with it would result in silent data loss.
The scenario requires a pretty foolish DBA, but still ...
ALTER TABLE on a composite type or ALTER TYPE on a table's rowtype.
We already rejected these cases, but the error messages were a bit
random and didn't always provide a HINT to use the other command type.
recovery stop time was used. This avoids a corner-case risk of trying to
overwrite an existing archived copy of the last WAL segment, and seems
simpler and cleaner all around than the original definition. Per example
from Jon Colverson and subsequent analysis by Simon.
since this will allow initdb to reject attempts to initdb in a locale
that uses such an encoding. We'll probably find out more such names
during beta ...
databases with encodings that are incompatible with the server's LC_CTYPE
locale, when we can determine that (which we can on most modern platforms,
I believe). C/POSIX locale is compatible with all encodings, of course,
so there is still some usefulness to CREATE DATABASE's ENCODING option,
but this will insulate us against all sorts of recurring complaints
caused by mismatched settings.
I moved initdb's existing LC_CTYPE-to-encoding mapping knowledge into
a new src/port/ file so it could be shared by CREATE DATABASE.
couldn't possibly HAVE_GETOPT. I believe this is the most appropriate
form of the patch submitted 2007-08-07 by Hiroshi Saito, though not
having a Windows build environment I won't know for sure till I see
the buildfarm results.
duplicative -DFRONTEND flags from many Makefiles. We still need Makefile

the same transaction can be identified even when no regular XID was assigned.
This seems essential after addition of the lazy-XID patch. Also some
minor code cleanup in write_csvlog().
happen condition can happen given incorrect input. The real problem is that
gram.y should try harder to distinguish * from "*" --- the latter is a legal
column name per spec, and someday we ought to treat it that way. However
fixing that is too invasive for a back-patch, and it's too late for the 8.3
cycle too. So just reduce the Assert to a plain elog for now. Per report
from NikhilS.
decompression of an already-compressed external value when we have to copy
it; save a few cycles when a value is too short for compression; and
annotate various lines that are currently unreachable.
- create a separate archive_mode GUC, on which archive_command is dependent
- %r option in recovery.conf sends last restartpoint to recovery command
- %r used in pg_standby, updated README
- minor other code cleanup in pg_standby
- doc on Warm Standby now mentions pg_standby and %r
- log_restartpoints recovery option emits LOG message at each restartpoint
- end of recovery now displays last transaction end time, as requested
by Warren Little; also shown at each restartpoint
- restart archiver if needed to carry away WAL files at shutdown

join search order portion of the planner; this is specifically intended to
simplify developing a replacement for GEQO planning. Patch by Julius
Stroffek, editorialized on by me. I renamed make_one_rel_by_joins to
standard_join_search and make_rels_by_joins to join_search_one_level to better
reflect their place within this scheme.
and up), per Chris Marcellino. This avoids consuming O(N^2) file
descriptors to support N backends. Tests suggest it's about a wash for
small installations, but large ones would have a problem.
