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.

columns.  Improved version of patch by mallah@trade-india.com.

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

RelOid_pg_class, and transaction locks XactLockTableId. RelId is renamed
to objId.

- LockObject() and UnlockObject() functions created, and their use
sprinkled throughout the code to do descent locking for domains and
types. They accept lock modes AccessShare and AccessExclusive, as we
only really need a 'read' and 'write' lock at the moment.  Most locking
cases are held until the end of the transaction.

This fixes the cases Tom mentioned earlier in regards to locking with
Domains.  If the patch is good, I'll work on cleaning up issues with
other database objects that have this problem (most of them).

7.3.2).  It removes some code duplication and #ifdeffing, and some
unstructured ugliness such as tacky breaks and an unneeded continue.
Breaks up a large function into smaller functions and reduces required
nesting levels, and kills a variable or two.

ltree_73.patch.gz - for 7.3 :
        Fix ~ operation bug: eg '1.1.1' ~ '*.1'

ltree_74.patch.gz - for current CVS
    Fix ~ operation bug: eg '1.1.1' ~ '*.1'
    Add ? operation
    Optimize index storage

Last change needs drop/create all ltree indexes, so only for 7.4

functions which limited the maximum date for a timestamp to AD 1465001.
The new limit is AD 5874897.
The files affected are:

doc/src/sgml/datatype.sgml:
    Documentation change due to patch. Included is a notice about
    the reduced range when using an eight-byte integer for timestamps.

src/backend/utils/adt/datetime.c:
    Replacement functions for j2date() and date2j() functions.

src/include/utils/datetime.h:
    Corrected a bug with the limit on the earliest possible date,
    Nov 23,-4713 has a Julian day count of -1. The earliest possible
    date should be Nov 24, -4713 with a day count of 0.

src/test/regress/expected/horology-no-DST-before-1970.out:
src/test/regress/expected/horology-solaris-1947.out:
src/test/regress/expected/horology.out:
    Copies of expected output for regression testing.
    Note: Only horology.out has been physically tested. I do not have access
    to a Solaris box and I don't know how to provoke the "pre-1970" test.

src/test/regress/sql/horology.sql:
    Added some test cases to check extended range.

in addition to int4. Thanks Janko Richter for contribution.

performance of min() and max() is slow when applied to the entire table,
and suggesting the simple workaround most experienced Pg users
eventually learn about (SELECT xyz ... ORDER BY xyz LIMIT 1).
