pgsql: Fix erroneous implementation of -s in postmaster.c (the switch - Mailing list pgsql-committers

Log Message:
-----------
Fix erroneous implementation of -s in postmaster.c (the switch doesn't take
an optarg).  Add some comments noting that code in three different files has
to be kept in sync.  Fix erroneous description of -S switch (it sets work_mem
not silent_mode), and do some light copy-editing elsewhere in postgres-ref.
