a relation's number of blocks, rather than the possibly-obsolete value
in pg_class.relpages. Scale the value in pg_class.reltuples correspondingly
to arrive at a hopefully more accurate number of rows. When pg_class
contains 0/0, estimate a tuple width from the column datatypes and divide
that into current file size to estimate number of rows. This improved
methodology allows us to jettison the ancient hacks that put bogus default
values into pg_class when a table is first created. Also, per a suggestion
from Simon, make VACUUM (but not VACUUM FULL or ANALYZE) adjust the value
it puts into pg_class.reltuples to try to represent the mean tuple density
instead of the minimal density that actually prevails just after VACUUM.
These changes alter the plans selected for certain regression tests, so
update the expected files accordingly. (I removed join_1.out because
it's not clear if it still applies; we can add back any variant versions
as they are shown to be needed.)

reliably (ie, regardless of which libraries they depend on). Also
make sure that we don't select headers that obviously belong to the
wrong one of the two libraries. This was discussed back around 4-Sep
but seems to have slipped through the cracks. The header selection
could be checked more closely, perhaps, but let's see if this is good
enough.

useful than just \'failed\' when there's a problem. Per gripe from
Chris Albertson.
In an unrelated change, use VACUUM FULL; VACUUM FREEZE; rather than
a single VACUUM FULL FREEZE command, to respond to my worries of a
couple days ago about the reliability of doing this in one go.

prevents problems when the DECLARE is in a portal and is executed
repeatedly, as is possible in v3 protocol. Per analysis by Oliver
Jowett, though I didn't use his patch exactly.

error conditions during regexp compile, but not during regexp execution;
any sort of "can't happen" errors would be treated as no-match instead
of being reported as they should be. Noticed while trying to duplicate
a reported Tcl bug.
to be processed by GUC before InitPostgres, because any required lookup
of the encoding conversion function has to be done during InitializeClientEncoding.
So, I broke this last week by moving GUC processing to after InitPostgres :-(.
What we can do as a compromise is process non-SUSET variables during
command line scanning (the same as before), and postpone the processing
of only SUSET variables. None of the SUSET variables need to be set
before InitPostgres.
