Is it?  Are we going to record dependency both ways, e.g primary table
-> foreign table and foreign table -> primary table, or just one of
them.  And when we see we depend on something, do we know always what it
could be.  If I drop a table and I depend on oid XXX, do I know if that
is a type, function, or serial sequence?
