latest fixes make it safe or not, but we won't find out if no one builds
it, eh?

Devel::PPPort instead.  Thanks to Gilles Darold for doing the legwork.

Fix for endian bug in TAR output
Nicer error messages in pg_dump

once per distinct LO, not once per pg_largeobject tuple.

as full as possible, seems better to use a tuple size around BLCKSZ/4
so that less space is wasted when a LO tuple is updated.  Also, this
lets us use a logical page size that's an exact power of two, avoiding
partial-page writes when client is sending us stuff in power-of-2
buffer chunks.

This used to make some sense under the old implementation, but now an
open LO is pretty darn cheap, so why restrict it?

kibitzing from Tom Lane.  Large objects are now all stored in a single
system relation "pg_largeobject" --- no more xinv or xinx files, no more
relkind 'l'.  This should offer substantial performance improvement for
large numbers of LOs, since there won't be directory bloat anymore.
It'll also fix problems like running out of locktable space when you
access thousands of LOs in one transaction.
Also clean up cruft in read/write routines.  LOs with "holes" in them
(never-written byte ranges) now work just like Unix files with holes do:
a hole reads as zeroes but doesn't occupy storage space.
INITDB forced!

testlo.c, except it's even skimpier on error checking :-(

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.

particular, allow linking with arbitrary commands rather than only $(AR) or
$(LD), and treat C++ without hacks.

Add option to disable shared libraries.  This takes the place of the
BSD_SHLIB variable.  The regression test driver ignores the plpgsql test
if there are no shared libraries available.

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.

as well allow DROP multiple INDEX, RULE, TYPE as well.  Add missing
CommandCounterIncrement to DROP loop, which could cause trouble otherwise
with multiple DROP of items affecting same catalog entries.  Try to
bring a little consistency to various error messages using 'does not exist',
'nonexistent', etc --- I standardized on 'does not exist' since that's
what the vast majority of the existing uses seem to be.

* 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.

and DropBuffers.  Formerly we cleared the flag for each buffer currently
belonging to the target rel or database, but that's completely wrong!
Must look at BufferTagLastDirtied to see whether the BufferDirtiedByMe
flag is relevant to target rel or not; this is *independent* of the
current contents of the buffer.  Vadim spotted this problem, but his
fix was only partially correct...

and destination of a tuple lie on the same page.
(Previously fixed in REL7_0 branch, now apply to current.)

This field stores the last allocated OID after the database was created.
Used by pg_dump in deciding what is user-defined vs. system-defined.

Um, Bruce, I've said several times that I didn't think Perchine's large
object changes should be applied until someone had actually reviewed
them.

Makefile.port, since they are of no use to configure and much of the
library magic happens in Makefile.port anyway.

Use __alpha, not __alpha__, since the former is universally available.
Remove -DNOFIXADE from the compile command line and put it in the port
include file.

I tested it restoring my database with > 100000 BLOBS, and dumping it out.
But unfortunatly I can not restore it back due to problems in pg_dump.
