Обсуждение: pgsql: Make sure that debug_query_string contains the original query

Log Message:
-----------
Make sure that debug_query_string contains the original query text,
if available (which it usually should be), during processing of Bind
and Execute protocol messages.  This improves usefulness of
log_min_error_statement logging for extended query protocol.
