You cannot unlock tables except by ending the transaction which took the lock. The first thing you should do is to make sure that all your database transactions are short. Also, you should nevr explicitly lock tables. Table locks are taken automatically by the SQL statements you are executing. Yours, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com
