Hi folks!

I Have a question, in a database are a table with many files (bytea) stored
(I support this database a don't design it), but we need delete many rows
(38000 rows approx),  but I when execute query:

BEGIN;
ALTER TABLE my_file_table DISABLE TRIGGER ALL;
DELETE FROM my_file_table WHERE id_table <> 230;

This query hang... 50 minutes and the query do not finish.

Any suggestion?
