commit    410fede0dd8e2effd05aa97baba9fe0fbb23b915
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Fri Mar 25 18:04:34 2005 +0000

    Fix two bugs in change_owner_recurse_to_sequences: it was grabbing an
    overly strong lock on pg_depend, and it wasn't closing the rel when done.
    The latter bug was masked by the ResourceOwner code, which is something
    that should be changed.
