Hi,
postgres_fdw reports no log message when it sends "ABORT TRANSACTION" etc
and gives up getting a reply from a foreign server because of timeout or
connection trouble. This makes the troubleshooting a bit harder when
using postgres_fdw.
So how about making postgres_fdw report a warning in that case?
Specifically I'm thinking to change pgfdw_get_cleanup_result()
in postgres_fdw/connection.c so that it reports a warning in case of
a timeout or connection failure (error of PQconsumeInput()).
BTW, pgfdw_get_cleanup_result() does almost the same things as
what pgfdw_get_result() does. So it might be good idea to refactor
those function to reduce the code duplication.
