[EMAIL PROTECTED] writes: > inability to restore infinity values via psql or pg_restore I don't think this has anything to do with a dump/restore problem. What it is is a problem with dealing with overflow in timestamp calculations. In current sources: regression=# select timestamp 'infinity' - timestamp '-infinity'; ?column? --------------------------------------------- 2147483647 days 2147483647:2147483647:00inf (1 row) AFAICT we don't have a concept of "infinity" for intervals, so this should raise an error instead of returning a bogus value. regards, tom lane
