PG_VERSION: 9.1.9
Arch: x86_64
OS: CentOS 6.5
We have a config-only setup (postgresql.conf exists not in $PGDATA). In postgresql.conf, external_pid_file is set and creates postmaster.pid in $PGDATA. Issuing “pg_ctl start”, the contents of postmaster.pid only ever contains one line, the process ID. It never contains any other lines, but according to specs, it’s supposed to have 7 lines. Any idea why postmaster.pid is only containing a single line, the process ID and no other lines?
