ALTER DATABASE <databasename> SET edb_user_login.enabled TO false;If user wants to execute some other specific procedure/function for user/database then following command allows that:
ALTER USER <username> SET edb_user_login.login_procedure_name TO '<schema>.procedure';
ALTER DATABASE <databasename> SET edb_user_login.login_procedure_name TO '<schema>.procedure';
