No -- this function handles just a single constraint, as identified by
OID. The recursion is handled by upper layers, which can be either
dependency.c or tablecmds.c. I think the problem you found is caused by
the fact that I worked with the tablecmds.c recursion and neglected the
one in dependency.c.
