close the current transaction.

At completion of each series of extended-query messages, the frontend
should issue a Sync message. This parameterless message causes the
backend to close the current transaction if it's not inside a
BEGIN/COMMIT transaction block (“close” meaning to commit if no
error, or roll back if error). Then a ReadyForQuery response is
issued. The purpose of Sync is to provide a resynchronization point
for error recovery. When an error is detected while processing any
extended-query message, the backend issues ErrorResponse, then reads
and discards messages until a Sync is reached, then issues
ReadyForQuery and returns to normal message processing. (But note
that no skipping occurs if an error is detected while processing Sync
— this ensures that there is one and only one ReadyForQuery sent for
each Sync.)
