I have modified following files.
bin/pg_ctl/pg_ctl.sh
include/miscadmin.h
backend/postmaster/poastmaster.c
backend/tcop/postgres.c
backend/utils/init/miscinit.c
The reason for the changes is to prevent starting postmaster if
(standalone) postgres is running and vice versa. Also, to know the pid
in postmaster.pid is postmaster or postgres, I set following
convention:
pid > 0: postmaster
pid < 0: (standalone) postgres
