pgsql: Tighten the concurrent abort check during decoding.

Tighten the concurrent abort check during decoding.

During decoding of an in-progress or prepared transaction, we detect
concurrent abort with an error code ERRCODE_TRANSACTION_ROLLBACK. That is
not sufficient because a callback can decide to throw that error code
at other times as well.
