Description kfm 2010-03-21 22:15:05 UTC

The attached patch implements a formal method for conveying error messages to the user in the event that pg_ctl fails to start postgres. This is accomplished in the following manner:

1) Using -d to daemonize so that we are able to capture stderr
   (as opposed to silent mode)

2) Using command substition syntax to perform the capturing process

3) Conveying the message as a secondary parameter to eend, should an error occur

NOTE: this patch also contains the fix detailed in bug 310045.

One way to test this patch is to change the ownership of the $PGDATA directory to root. That will prevent postgres from starting and, rather than displaying no meaningful message to the user, it should terminate as thus:

* Starting PostgreSQL ...
pg_ctl: could not open PID file "/var/lib/postgresql/8.4/data/postmaster.pid": Permission denied  [ !! ]
 * ERROR: postgresql-8.4 failed to start

Oops, last patch introduced an unintended change relative to the existing script. This one is good.
