Hello, PostgreSQL 11.6 (Debian 11.6-2~sid1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 9.2.1-21) 9.2.1 20191130, 64-bit Is there something awry with the pg_prepared_statements view? This is the only row found and it is NOT created by the application. name statement prepare_time parameter_types from_sql S_1 ROLLBACK 2020-01-21 12:35:35.031257 {} false In the development environment every statement is logged, however for some reason the DEALLOCATE's never appear in the logs. This could be caused by the view not recording the prepared statement, as the DEALLOCATE is only made if the prepared statement name exists in the view. max_prepared_transactions = 6 is the value set in postgresql.conf. TIA, Robert
