fa9357d0b7 Fix AbortOutOfAnyTransaction logic to avoid notice about
'AbortTransaction and not in in-progress state' when client disconnects
just after an error.  Notice seems pretty harmless, so I'm not going
to worry about back-patching this into 7.0.* ...

dea7d54151 If a field is incompressible ('compressed' data is actually larger than
source, due to addition of header overhead), store it as plain data
rather than pseudo-compressed data.  This saves a few microseconds when
reading it out, but much more importantly guarantees that the toaster
won't actually expand tuples that contain incompressible data.  That's
essential to avoid 'Tuple too big' failures with large objects.

4b65a2840b New relcache hash table with RelFileNode as key to be used
from bufmgr - it would be nice to have separate hash in smgr
for node <--> fd mappings, but for the moment it's easy to
add new hash to relcache.
Fixed small bug in xlog.c:ReadRecord.

fba790ad58 Makeover for Unixware 7.1.1
* Makefile: Add more standard targets.  Improve shell redirection in GNU
make detection.
* src/backend/access/transam/rmgr.c: Fix incorrect(?) C.
* src/backend/libpq/pqcomm.c (StreamConnection): Work around accept() bug.
* src/include/port/unixware.h: ...with help from here.
* src/backend/nodes/print.c (plannode_type): Remove some "break"s after
"return"s.
* src/backend/tcop/dest.c (DestToFunction): ditto.
* src/backend/nodes/readfuncs.c: Add proper prototypes.
* src/backend/utils/adt/numutils.c (pg_atoi): Cope specially with strtol()
setting EINVAL. This saves us from creating an extra set of regression test
output for the affected systems.
* src/include/storage/s_lock.h (tas): Correct prototype.
* src/interfaces/libpq/fe-connect.c (parseServiceInfo): Don't use variable
as dimension in array definition.
* src/makefiles/Makefile.unixware: Add support for GCC.
* src/template/unixware: same here
* src/test/regress/expected/abstime-solaris-1947.out: Adjust whitespace.
* src/test/regress/expected/horology-solaris-1947.out: Part of this file
was evidently missing.
* src/test/regress/pg_regress.sh: Fix shell.  mkdir -p returns non-zero if
the directory exists.
* src/test/regress/resultmap: Add entries for Unixware.

925418d2fa Ensure that catcache 'busy' flags are reset at transaction abort.
Without this, an elog during cache-entry load leaves that catcache
unusable.  elog in that segment of code is pretty unusual but it can
happen.

dd8ad64118 Fix tuptoaster bugs induced by making bytea toastable. Durn thing was
trying to toast tuples inserted into toast tables!  Fix is two-pronged:
first, ensure all columns of a toast table are marked attstorage='p',
and second, alter the target chunk size so that it's less than the
threshold for trying to toast a tuple.  (Code tried to do that but the
expression was wrong.)  A few cosmetic cleanups in tuptoaster too.
NOTE: initdb forced due to change in toaster chunk-size.

61aca818c4 Modify heap_open()/heap_openr() API per pghackers discussion of 11 July.
These two routines will now ALWAYS elog() on failure, whether you ask for
a lock or not.  If you really want to get a NULL return on failure, call
the new routines heap_open_nofail()/heap_openr_nofail().  By my count there
are only about three places that actually want that behavior.  There were
rather more than three places that were missing the check they needed to
make under the old convention :-(.

3a9a74a09d Convert all remaining geometric operators to new fmgr style. This
allows fixing problems with operators that expected to be able to
return a NULL, such as the '#' line-segment-intersection operator
that tried to return NULL when the two segments don't intersect.
(See, eg, bug report from 1-Nov-99 on pghackers.)  Fix some other
bugs in passing, such as backwards comparison in path_distance().

421f0baaff Further cleanup of btbuild (CREATE INDEX). Avoid storing unneeded
left keys during bottom-up index build, and leave some free space
instead of packing the pages to the brim (so as to avoid vast numbers
of page splits during the first interactive insertions).

9e85183bfc Major overhaul of btree index code. Eliminate special BTP_CHAIN logic for
duplicate keys by letting search go to the left rather than right when an
equal key is seen at an upper tree level.  Fix poor choice of page split
point (leading to insertion failures) that was forced by chaining logic.
Don't store leftmost key in non-leaf pages, since it's not necessary.
Don't create root page until something is first stored in the index, so an
unused index is now 8K not 16K.  (Doesn't seem to be as easy to get rid of
the metadata page, unfortunately.)  Massive cleanup of unreadable code,
fix poor, obsolete, and just plain wrong documentation and comments.
See src/backend/access/nbtree/README for the gory details.

6bfe64032e Cleanup of code for creating index entries. Functional indexes with
pass-by-ref data types --- eg, an index on lower(textfield) --- no longer
leak memory during index creation or update.  Clean up a lot of redundant
code ... did you know that copy, vacuum, truncate, reindex, extend index,
and bootstrap each basically duplicated the main executor's logic for
extracting information about an index and preparing index entries?
Functional indexes should be a little faster now too, due to removal
of repeated function lookups.
CREATE INDEX 'opt_type' clause is deimplemented by these changes,
but I haven't removed it from the parser yet (need to merge with
Thomas' latest change set first).

badce86a2c First stage of reclaiming memory in executor by resetting short-term

quals or projections are handled.  Clean up some old dead cruft in
