Hello
The postmaster command does not list "--config-file" in its help
although that parameter is understood:
$ /usr/lib/postgresql/9.2/bin/postmaster --help | grep -c config-file
0
$ /usr/lib/postgresql/9.2/bin/postmaster
postgres does not know where to find the server configuration file.
You must specify the --config-file or -D invocation option or set the
PGDATA environment variable.
$ /usr/lib/postgresql/9.2/bin/postmaster --version
postgres (PostgreSQL) 9.2.2
bye,
