Fix psql's \copy command to ensure that it cycles libpq back to the idle state
(in particular, causing the ReadyForQuery message to be eaten) beforereturning from do_copy. The only known consequence of failing to do so isthat get_prompt might show a wrong result for the %x transaction statusescape, as reported by Bernd Helmle; but it's possible there are other issues.Back-patch as far as 7.4, the oldest version supporting %x.
