b4def32439 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

449020f782 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.

03d5c070f0 Modify the outer join placeholder code with something closer to working 
code. Works here, but not completely implemented past this point.

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.

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.
