CPP) to create platform independent files. Unfortunately, that means that
every config.status (or configure) run invariably causes a relink of the
postmaster and also that we can't put these files in the distribution
(usefully). So we make it a little smarter: when the output files already
exist and it notices that it would recreate them in identical form, it
doesn't touch them. In order to avoid re-running the make rule all the time
we update a timestamp file instead.

Update release_prep accordingly. Also make Gen_fmgrtab.sh use the awk that
is detected at configure time, not necessarily named `awk' and have it check
for exit statuses a little better.

In other news... Remove USE_LOCALE from the templates, it was set to `no'
everywhere anyway. Also remove YACC and YFLAGS from the templates, configure
is smart enough to find bison or yacc itself. Use AC_PROG_YACC for that
instead of the hand-crafted code. Do not set YFLAGS to `-d'. The make rules
that need this flag should explicitly invoke it. YFLAGS should be a user
variable. Update the makefiles to that effect.

configuration helper things into config/ dir. Adjusted some relative paths
in makefiles.

over multiple lookups --- it should use SearchSysCacheTupleCopy instead.
This accounts for rare failures like 'init_fcache: null probin for procedure 481'
when running concurrently with a VACUUM.

direct pointer into the syscache entry for the type.  In some cases
the syscache entry might get flushed before we are done using the
returned type name.  This bug accounts for difficult-to-repeat
failures seen when INSERTs into columns of certain data types are
run in parallel with VACUUMs of system tables.  There may be related
problems elsewhere --- we need to take a harder look at uses of
syscache data.

Added org/postgresql/DriverClass.java to the list of files removed by make clean (it's dynamically built)
Fixed Statement, so that the update count is valid when an SQL DELETE operation is done.
While fixing the update count, made it easier to get the OID of the last insert as well. Example is in example/basic.java

inputs have been converted to newstyle.  This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters.  Still
more to do for the Alpha port however.

no reason for them to be copied into src/backend rather than being
installed straight from the catalog subdirectory.  This also avoids
some peculiar behavior (bugs?) present in at least gmake 3.78.1: it
won't always update the bki files in backend/ even when the ones in
backend/catalog/ are newer.

that name and issue a NOTICE to the effect that we did.  Previously,
code would try to assign the new cursor declaration to the old portal,
but this didn't work reliably since new parsetree is still sitting in
blank portal and is likely to get clobbered.

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.

Clean up some funny business in the config file code.

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!)
