Description
According to the protocol specifications, even in SimpleQuery mode/ subprotocol, it is possible to have multiple statements in a Simple Query.
Get some pcaps with this scenario and see how the parser behaves.
(cf https://www.postgresql.org/docs/13/protocol-flow.html#id-1.10.5.7.4)
We'll currently create a new transaction when we receive a SimpleQuery message. But what happens with multiple statements for:
- parsing
- consolidating data, if need be
- logging

We do have tests with multiple-statement queries, but still thinking this deserves a review.

Jason demonstrated that if a simple query message contains two queries, the parser will process the responses as if only one query existed.
Will add an SV soon.
