I looked at this bug report from September. The problem is that
LookupExplicitNamespace() doesn't have a missing_ok parameter, even
though get_namespace_oid(), which it calls, does. By adding a
missing_ok parameter and passing it cleanly, I fixed the problem:
test=> DROP TABLE IF EXISTS foo.bar;
NOTICE: table "bar" does not exist, skipping
DROP TABLE
Patch attached.
