I found a few problems: (1) The patch doesn't apply to HEAD. Could you rebase your patch? patching file src/bin/pg_ctl/pg_ctl.c Hunk #1 FAILED at 453. 1 out of 1 hunk FAILED -- saving rejects to file src/bin/pg_ctl/pg_ctl.c.rej (2) Although I haven't tried, doesn't pg_ctl start fail on non-Windows platforms because of the following check? ! if (opt == '-') ! ereport(ERROR, ! (errcode(ERRCODE_SYNTAX_ERROR), ! errmsg("--%s requires a value", ! optarg))); And, in the postgres reference page, http://www.postgresql.org/docs/devel/static/app-postgres.html there's a paragraph: "The -- options will not work on FreeBSD or OpenBSD. Use -c instead. This is a bug in the affected operating systems; a future release of PostgreSQL will provide a workaround if this is not fixed." Would --background work on FreeBSD and OpenBSD (i.e. would pg_ctl start succeed)? I don't have access to those platforms. (3) --background will also be used by restart subcommand, won't it? + in a console window. It is used automatically by + <command>pg_ctl</command> when called with the + <option>start</option> subcommand. Regards MauMau
