  commit, but I am adding it now so it is in CVS.]

The patch basically is a slight rearrangement of the code to allow
fork/exec on Unix, with the ultimate goal of doing CreateProcess on
Win32.  The changes are:

        o  Write out postmaster global variables and per-backend
variables to be read by the exec'ed backend

        o  Mark some static variables as global when exec is used so
then can be dumped from postmaster.c, marked NON_EXEC_STATIC

        o  Remove value passing with -p now that we have per-backend
file

        o  Move some pointer storage out of shared memory for easier
dumping.

        o  Modified pgsql_temp directory cleanup to handle per-database
directories and the backend exec directory under datadir.

to step more than one entry after descending the search tree to arrive at
the correct place to start the scan.  This can improve the behavior
substantially when there are many entries equal to the chosen boundary

  a) ones that are 100% backward (such as the comment about
     outputting this format)
and
  b) ones that aren't (such as deprecating the current
     postgresql shorthand of
         '1Y1M'::interval = 1 year 1 minute
     in favor of the ISO-8601
         'P1Y1M'::interval = 1 year 1 month.

Attached is a patch that addressed all the discussed issues that
did not break backward compatability, including the ability to
output ISO-8601 compliant intervals by setting datestyle to
iso8601basic.

Interval values can now be written as  ISO 8601 time intervals, using
the "Format with time-unit designators". This format always starts with
the character 'P', followed  by a string of values followed
by single character time-unit designators. A 'T' separates the date and
time parts of the interval.
