Include some new code for outer joins. Disabled by default, but enable by
including the following in your Makefile.custom:
CFLAGS+= -DENABLE_OUTER_JOINS -DEXEC_MERGEJOINDEBUG
Put in explicit checks for implicit index name lengths.
Put in hooks for outer joins by passing a few parameters back and forth
in function calls. May not be close to working yet.
Bring debugging print statement declarations up to date.
Comment-out the #undef default declarations to allow the parameters to be
set on the compiler command line.
Rearrange order of subdirectory creation to help generate parse.h
file early enough to use in nodes/.
Try to be more complete for rules on generating parse.h,
but it still does not work any better than before. Should be able to
make correctly if parser/gram.y is updated even without a "make clean"
but so far not there yet.

Ok. I found an align problem in lobj that might not appear other than
Solaris/sparc. Please apply included patches to
src/backend/storage/large_object/inv_api.c and try again. (These are

Repair some pretty serious problems in dynahash.c and
shared memory space allocation. It's a wonder we have not seen bug
reports traceable to this area ... it's quite clear that the routine
dir_realloc() has never worked correctly, for example.

Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef
NOT_USED" for current. I have tested these patches in that the
postgres binaries are identical.

Rearrange handling of MAXBACKENDS a little bit. The default setting
of MAXBACKENDS is now 1024, since all it's costing is about 32 bytes of memory
per array slot. configure's --with-maxbackends switch now controls DEF_MAXBACKENDS
which is simply the default value of the postmaster's -N switch. Thus,
the out-of-the-box configuration will still limit you to 64 backends,
but you can go up to 1024 backends simply by restarting the postmaster with
a different -N switch --- no rebuild required.
Tom Lane [Fri, 19 Feb 1999 06:06:39 +0000 (06:06 +0000)]
Allow maximum number of backends to be set at configure time
(--with-maxbackends). Add a postmaster switch (-N backends) that allows
the limit to be reduced at postmaster start time. (You can't increase it,
sorry to say, because there are still some fixed-size arrays.)
Grab the number of semaphores indicated by min(MAXBACKENDS, -N) at
postmaster startup, so that this particular form of bogus configuration
is exposed immediately rather than under heavy load.

Fix optimizer coredump with unary-operator WHERE clauses.
A test case is:
create table linetab (x line);
select * from linetab where ?| x;
which coredumps in 6.4.2 and current sources.
Change #if FALSE to #if NOT_USED to avoid port problems.
Fix problem with date_part() for timespan (had an offset of one)
when given decade, century, and millenium as arguments.
Reported by Ricardo J.C.Coelho.
Add routines to convert between int8 and text/varchar types.
Change #if FALSE to #if NOT_USED to avoid port problems.
Fix up pg_indent weirdness with function argument declarations.
Describe the date/time parsing rules.
Include specific information on the supported time zones.
It's a really big table, so maybe it should go into an appendix instead.
Substitute great info from Stefan Simkovics' Master's Thesis.
Still need to add some acknowledgements at the top of the doc;
already have full info in the bibliography but since the original is
being spread across the existing docs we should also mention things
locally.
