actually use their targetlist, are given a targetlist that is just a
pointer to the first appended plan's targetlist.  This is OK, but what
is not OK is that any sub-select expressions in said tlist were being
entered in the subPlan lists of both the Append and the first appended
plan.  That led to two startup and two shutdown calls for the same
plan node at exec time, which led to crashes.  Fix is to not generate
a list of subPlans for an Append node.  Same problem and fix apply
to other node types that don't have a real, functioning targetlist:
Material, Sort, Unique, Hash.

configuration options `Log_timestamp' and `Log_pid'.

Install a default configuration file.

Clean up some funny business in the config file code.

"rb" and "wb".

to do it at the last moment before calling system() ... not at some
randomly-chosen earlier point in the routine ...

it will close VFDs if necessary to surmount ENFILE or EMFILE failures.
Make use of this in md.c, xlog.c, and user.c routines that were
formerly vulnerable to these failures.  In particular, this should
handle failures of mdblindwrt() that have been observed under heavy
load conditions.  (By golly, every other process on the system may
crash after Postgres eats up all the kernel FDs, but Postgres will
keep going!)

conditional expression x?y:z in an awk program.  Seems old versions
of awk don't have that ...

overlength quoted identifiers.  Death and destruction ensue...

the prototype in guc.h.  The following patch corrects that.

some versions of gmake (mine didn't do the right thing, anyway).

(ie, parameters instead of consts) will be treated as a range query.
We do not know the actual selectivities involved, but it seems like
a good idea to use a smaller estimate than we would use for two unrelated
inequalities.

That means you can now set your options in either or all of $PGDATA/configuration,
some postmaster option (--enable-fsync=off), or set a SET command. The list of
options is in backend/utils/misc/guc.c, documentation will be written post haste.

pg_options is gone, so is that pq_geqo config file. Also removed were backend -K,
-Q, and -T options (no longer applicable, although -d0 does the same as -Q).

Added to configure an --enable-syslog option.

changed all callers from TPRINTF to elog(DEBUG)

AUTHTYPE in config file.  Patch both branches.
