title: How to disable connection pooling with PostgreSQL in flask-sqlalchemy?
body: <p>I want to use <a href="http://www.pgpool.net/mediawiki/index.php/Main_Page" rel="nofollow">pgpool</a> or <a href="https://wiki.postgresql.org/wiki/PgBouncer" rel="nofollow">pgbouncer</a> as an external connection pooler with my flask app. The <a href="https://pythonhosted.org/Flask-SQLAlchemy/index.html" rel="nofollow">flask-sqlalchemy</a> extension does not seem to expose a way to change the connection pooler to <a href="http://docs.sqlalchemy.org/en/latest/core/pooling.html#sqlalchemy.pool.NullPool" rel="nofollow">NullPool</a>. Is there some way to do this?</p>
