Re: JDBC String to Bool spec

Thanks… is there a reason those tables were dropped from the 4.2 spec PDF?

This conversion succeeds because the driver (both pgjdbc & ng) fallback to decoding the column as a double then converting that by testing it “== 1”; which seems valid but questionable since “!= 0” would also be valid, but vastly different.
