2a76aa23e0 We have to return dummy tuple for empty targetlist!
Try select t1.x from t1, t2 where t1.y = 1 and t2.y = 1
- t2 scan target list will be empty and so no one tuple
will be returned...

a431aaec44 Export include/utils/mcxt.h so that external stuff can include
palloc.h again.  Move exporting of backend header files out of libpq's
Makefile (whatever was it doing there in the first place?) and into
backend/Makefile.

731603a92b A few further tweaks to shared memory space estimation.
This change brings the default size of the main shmem block back under 1MB,
which is a fairly popular value for the kernel's SHMMAX parameter.

e0345e09bf Partial fix for copied-plan bugs reported by Hiroshi Inoue:
_copyResult didn't copy subPlan structure completely.  _copyAgg is still
busted, apparently because of changes from EXCEPT/INTERSECT patch
(get_agg_tlist_references is no longer sufficient to find all aggregates).
No time to look at that tonight, however.

b204d10c79 Executor no longer cares about mergejoinop, mergerightorder, mergeleftorder,
so remove them from MergeJoin node.  Hack together a partial
solution for commuted mergejoin operators --- yesterday
a mergejoin int4 = int8 would crash if the planner decided to
commute it, today it works.  The planner's representation of
mergejoins really needs a rewrite though.
Also, further testing of mergejoin ops in opr_sanity regress test.

02fa3e4394 Thank you for the advice. I concluded that current inet code has a
portability problem. Included patches should be applied to both
current and 6.4 tree. I have tested on LinuxPPC, FreeBSD and Solaris
2.6. Now the inet regression tests on these platforms are all happy.

348ab94822 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.

bcfdc9df04 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.

23c30246d7 pathkeys.c cleanup. 1999-02-21 01:55:03 +00:00
Tom Lane
9d197856dd 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.

e77b630cf0 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.
