cleaning out temp namespaces.  We don't really want the server log to be
cluttered with 'Drop cascades to table foo' every time someone uses a
temp table...

problems in applications that may have a large number of files open,

at database shutdown, and then load it again at database startup.  This
preserves our hard-won knowledge of free space across restarts (given
an orderly shutdown, that is).

DELETE with inherited target table.  Fix it; add a regression test.
Also, correct ancient misspelling of 'inherited'.

DELETE of an inheritance tree references another inherited relation.
This bug has been latent since 7.1; I'm still not quite sure why 7.1 and
7.2 don't manifest it (at least, they don't crash on a simple test case).

Adjustable threshold is gone in favor of keeping track of total requested
page storage and doling out proportional fractions to each relation
(with a minimum amount per relation, and some quantization of the results
to avoid thrashing with small changes in page counts).  Provide special-
case code for indexes so as not to waste space storing useless page
free space counts.  Restructure internal data storage to be a flat array
instead of list-of-chunks; this may cost a little more work in data
copying when reorganizing, but allows binary search to be used during
lookup_fsm_page_entry().

as are non-amindexnulls AMs unless first column is attnotnull.

pg_description entries, so I did not force initdb.

the join, per recent discussion on pgsql-sql.  Not clear that this will
come up often in real queries, but it's not any more expensive to do it
right, so we may as well do it right.

tupdesc even with zero tuples returned: some plpgsql routines assumed
they didn't need to do SPI_freetuptable() after retrieving no tuples.

is assumed to be in local time, not GMT.  This improves consistency with
other operations, which all assume local timezone when it matters.  Per
bug #897.

a string that could not be dropped into a query.

Minor code restructuring to make it easier to catch recursive case.

Allow whenever statement to list function without parameters.

end of a btree index.  This isn't super-effective, since we won't move
nondeletable pages, but it's better than nothing.  Also, improve stats

deleting multiple index entries on a single index page.  This makes for
a very substantial reduction in the amount of WAL traffic during a
large delete operation.

service it until after we execute SetThisStartUpID().  Else shutdown
process will write the wrong SUI into the shutdown checkpoint, which
seems likely to be trouble --- although I've not quite figured out
how significant it really is.

setting timezone-related variables during transaction start.  They were
not used anyway in platforms that HAVE_TM_ZONE or HAVE_INT_TIMEZONE,
which it appears is *all* the platforms we are currently supporting.
For platforms that have neither, we now only support UTC or numeric-
offset-from-UTC timezones.
