commit    79fcde48b229534fd4a5e07834e5e0e84dd38bee
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Sun Nov 29 01:51:56 1998 +0000
First released in: 6.5, 6.4.2

    Portability fix for old SunOS releases: fflush(NULL)
    doesn't work there.  Fortunately the postmaster only has stdout and
    stderr to flush.
