to be initialized with proper values. Affected parameters are
fillfactor, analyze_threshold, and analyze_scale_factor.
Especially uninitialized fillfactor caused inefficient page usage
because we built a StdRdOptions struct in which fillfactor is zero
if any reloption is set for the toast table.
In addition, we disallow toast.autovacuum_analyze_threshold and
toast.autovacuum_analyze_scale_factor because we didn't actually
support them; they are always ignored.

Analysis by Tom Lane and Alvaro Herrera. Patch by me.
Backpatch to 8.4.
and current server clock time to SR data messages. These are not currently
used on the slave side but seem likely to be useful in future, and it'd be
better not to change the SR protocol after release. Per discussion.
Also do some minor code review and cleanup on walsender.c, and improve the
protocol documentation.
"val AS name" to "name := val", as per recent discussion.
This patch catches everything in the original named-parameters patch,
but I'm not certain that no other dependencies snuck in later (grepping
the source tree for all uses of AS soon proved unworkable).
In passing I note that we've dropped the ball at least once on keeping
ecpg's lexer (as opposed to parser) in sync with the backend. It would
be a good idea to go through all of pgc.l and see if it's in sync now.
I didn't attempt that at the moment.
table with foreign key constraints eats memory. Per off-line discussion of
bug #5480 with its reporter. Also do some minor wordsmithing elsewhere in
the same section.
move two paragraphs that apply to log shipping in general from the
"Alternative method for log shipping" section to the earlier sections.
Add varname tags where missing. Some small wording changes.
RELEASE SAVEPOINT to make an older savepoint with the same name
accessible. It's also possible to implicitly release the savepoint by
rolling back to an earlier savepoint, but mentioning that too would make
the note just more verbose and confusing.
