I'm not sure if this can be of any help, but to me it looks like you somehow need to explicitly specify the start DB for your connection (e.g. start researching from how to specify the default DB for the connection).

>Has anyone used pgBouncer with VFP9? I have been using Postgres for a few years now and everything works fine with VFP9. Today I thought I would try pgBouncer for connection pooling. However, no matter what I do using the SQLStringConnect() with pgBouncer it always tells me no such database. Yet the database does exist and is named correctly in the pgBouncer.ini file. So I wondering what is causing the error.
