Could still be a permission problem. Whatever NT account you are using as the service account (usally called postgres) for the PostgreSQL server is the one that needs to be able to create the postmaster.pid. Make sure that account has full rights to the data folder. Hope that helps, Regina -----Original Message----- From: pgsql-general-owner@xxxxxxxxxxxxxx [mailto:pgsql-general-owner@xxxxxxxxxxxxxx] On Behalf Of Abraham, Danny Sent: Monday, December 24, 2007 9:38 AM To: pgsql-general@xxxxxxxxxxxxxx Subject: pg_ctl start fails on Windows The error message is "could not open PID file". I can manually create the file "postmaster.pid", so the problem Does not look like a permission problem.
