Hello, I have a legacy database that I'm looking to user2d2-postgres w/ (Teiid) that implements a PostgreSQL compatible API. Unfortunately it doesn't support passing in blank queries as described by the PostgreSQL spec.

Debugging thread here:sfu-db/connector-x#107

Would you be open to switching the probe query foris_valid to something more standard, likeSELECT 1;, or at least make this configurable? This would allow me (and others) to retain connection pooling functionality in that case.

I noticedSELECT 1; is actually what is recommended upstream in r2d2 for connection pool implementors, and understand the empty query is probably slightly faster round trip.

Thanks!
