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.

query string.  This fixes a bug where bool types sometimes returned with
a string that could not be dropped into a query.

recursion in RewriteQuery(); also, detect recursion in fireRIRrules(),
so as to catch self-referential views per example from Ryan VanderBijl.
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
displayed during VACUUM VERBOSE.

older than current Xmin; we don't have to wait till it's older than
GlobalXmin.

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.

to fix, but it seems to basically work...

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.

now knows what to do upon hitting a dead page (in theory anyway, it's
untested...).  Add a post-VACUUM-cleanup entry point for index AMs, to
provide a place for dead-page scavenging to happen.
Also, fix oversight that broke btpo_prev links in temporary indexes.
initdb forced due to additions in pg_am.

support btree compaction, as per proposal of a few days ago.  btree index
pages no longer store parent links, instead they have a level indicator
(counting up from zero for leaf pages).  The FixBTree recovery logic is
removed, and replaced by code that detects missing parent-level insertions
during WAL replay.  Also, generate appropriate WAL entries when updating
btree metapage and when building a btree index from scratch.  I believe
btree indexes are now completely WAL-legal for the first time.
initdb forced due to index and WAL changes.

answer when SET TIMEZONE has been done since the start of the current
transaction.  Per bug report from Robert Haas.
I plan some futher cleanup in HEAD, but this is a low-risk patch for
the immediate issue in 7.3.

- more work from the SGML police

- some grammar improvements: rewriting a paragraph or two, replacing
contractions where (IMHO) appropriate

- fix missing utility commands in lock mode docs

- improve CLUSTER, REINDEX, SET SESSION AUTHORIZATION ref pages

implementation
of '\e' history tracking for systems that have a readline compatability
library without replace_history_entry.  I fall back to pushing the query
onto the history stack after the \e, rather than replacing it.

The patch adds one more place to look for readline headers, and a test
for replace_history_entry. I've only included the patch for configure.in
