Umm, that doesn't look right. For queries against pg_description you need to specify the classoid (in this case 'pg_class'::regclass) as well as the objoid (and possibly the objsubid). Remember, Oids are not unique across the whole catalog. I looks to me like here one rwo is picking up a description for an entry in some other catalog
Doh! I knew I was forgetting something. This is indeed a bug in the JDBC driver. In the query results a few messages above one is in catalog 1255 and the other (correct one) is in 1259.
