Suddenly, i started getting some weird errors with a table named xx: db=> drop sequence xx_cod_seq; ERROR: DeleteTypeTuple: xx_cod_seq type nonexistent db=> drop table xx; ERROR: mdopen: couldn't open xx_pkey: No such file or directory Then, i noticed the file xx_pkey wasnt at the base directory anymore, so i create a null file and droped the primary key. Now, I get this error while trying to drop the table : db=> drop table xx; ERROR: DeleteTypeTuple: xx type nonexistent Ï don't know how it happened, but i noticed that this table isnt on pg_type. Can some help me ???? How do I fix that so i can't drop this table ? And how did it happen ? Regards, Gustavo Henrique Maultasch de Oliveira [EMAIL PROTECTED]
