Bug Fixes:

• Fixed ParseComplete desynchronization in pipeline on errors: Fixed a protocol desynchronization issue (especially noticeable in .NET Npgsql driver) where synthetic ParseComplete messages were not being inserted if an error occurred during a pipelined batch. When the pooler caches a prepared statement and skips sending Parse to the server, it must still provide a ParseComplete to the client. If an error occurs before subsequent commands are processed, the server skips them, and the pooler now ensures all missing synthetic ParseComplete messages are inserted into the response stream upon receiving an ErrorResponse or ReadyForQuery.

• Fixed incorrect use_savepoint state persistence: Fixed a bug where the use_savepoint flag (which disables automatic rollback on connection return if a savepoint was used) was not reset after a transaction ended.
