Yeah, getting rid of references to the user in ACL lists is going to
be the main pain-in-the-neck here. Ownership is relatively easy to fix
with direct updates on the catalog owner columns (and in 7.4 there's
by definition nothing behind-the-scenes in dependency tables). I
can't think of any equally easy fix for ACL references though, because
the available SQL-level operations on aclitem arrays are pretty weak.

choose an index scan if your joining column's datatypes do not
match
