Use newly introduced procd_add_restart_mount_trigger to make sure postmaster gets started only once PGDATA becomes available. Relocate socket directory to /var/lib/postgresql to make it possible to run postgresql inside a ujail. Use signal for shutdown, so it works nicely with jail. Allow multiple script in UCI 'config postgres-db' to be a list and run them in order listed. User more silent methods to check for db or role existence and make it easy to create several databases owned by the same user by passing the same credentials multiple times. Remove disfunctional reload handler. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
