This has to do with the way you've configured pgBouncer to deal with connections. It keeps a pool of connections open and randomly assigns one to your query.
I don't know the specifics of how it forwards your queries to actual connections.
As for the prepared statements: they are created on-demand. But it might be interesting to have a way to initialize a new connection and just prepare all statements eagerly. That should fix your problem.

Unfortunately I don't have direct control over the PgBouncer configuration. Fortunately I can bypass it and connect directly, which will work okay for now.
According to this page in the PgBouncer FAQ, it's necessary to avoid using prepared statements at all when it's configured in transaction pooling mode. It would be great to be able to switch off the use of prepared statements for cases like this.
We're looking into using pq
in a fairly big way, and if it proves successful we could look into implementing a flag to disable the prepared extensions when instantiating PQ()
