Log message:
    [ This description should have been on the earlier fork/exec
    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.
