Yeah. What file names are actually present in $PGDATA/pg_clog/, and what does pg_controldata say about the current XID counter? We have seen some bugs where clog files get deleted before they're not needed anymore :-( Also, can you show us the pg_filedump output for the page of pg_description you think is trashed? I find "-i -f" options give the most useful output usually. regards, tom lane
