In order to increase performance, PostgREST uses prepared statements by default. However, this setting is incompatible with connection poolers such as PgBouncer working in transaction pooling mode. In this case, you need to set the :ref:`db-prepared-statements` config option to ``false``. On the other hand, session pooling is fully compatible with PostgREST, while statement pooling is not compatible at all.
