The usage of null as the last parameter for table types makes the driver
return only the default table types, not all of getTableTypes().  Things
like "SYSTEM TABLE" are not included in the default list so this is why
you get nothing from information_schema and pg_catalog.  Re-reading the
javadoc, it says "types - a list of table types to include; null returns
all types".  So clearly we're in violation of that.  Will look at a fix.
