Pass along with_raw_connection params in PG adapter

Prior to this commit we were passing `allow_retry` and
`materialize_transactions` through from `execute_and_clear` to
`exec_cache`/`exec_no_cache`, but then doing nothing with them.

We've got a few internal queries using `execute_and_clear` (mostly via
`internal_exec_query`) that are passing `allow_retry: true` and
`materialize_transactions: false`. These calls will fail on connection
errors that might have been retryable. It's also possible they are
materializing transactions earlier than expected (although probably
not—most of the methods look like they would be called only by us,
always outside a transaction).

This commit forwards the arguments through to `with_raw_connection` so
the callers get the behavior they likely expect.
