Hi there,
In general, no, you should not see issues. We (really, Avatica -- the
project "powering" PQS) strives to make changes to the wire-protocol in
a backwards compatible manner. Avatica also includes a basic framework
to do forward and backwards compatibility testing.
You are more likely to run into issues where the 4.7 client is simply
doing the wrong thing. There have been one or two issues like these.
CALCITE-1103 is one that I can find easily (truncation around decimal
datatypes).

Would we run into issues when working with a newer PQS server (4.11) and
a 4.7 client library? In general I'm curious if there is backward
compatibility between mixed server / client versions.
Thanks
