Thanks. This is real interesting, because none of the rows have xmax/cmax set, so it doesn't appear that they were meant to have been updated out of existence. > For the at_dns table, it appears one column (ac_soa_serial) changes. Does that correspond to something your application does, ie UPDATE ac_soa_serial to a new value without changing anything else? I'm trying to guess if the duplicates arose by means of a misfiring UPDATE, or if they were independent insertions. Is it plausible that two rows that are the same except for ac_soa_serial would be inserted by your app? If the latter, a possible theory is that the OID counter is somehow being rolled back by the dump/reload process. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
