postgres_fdw: Fix unexpected reporting of empty message.
pgfdw_report_error() in postgres_fdw gets a message from PGresult or
PGconn to report an error received from a remote server. Previously
if it could get a message from neither of them, it reported empty
message unexpectedly. The cause of this issue was that pgfdw_report_error()
didn't handle properly the case where no message could be obtained
and its local variable message_primary was set to '\0'.
This commit improves pgfdw_report_error() so that it reports the message
"could not obtain ..." when it gets no message and message_primary
is set to '\0'. This is the same behavior as when message_primary is NULL.
dblink_res_error() in dblink has the same issue, so this commit also
improves it in the same way.
Back-patch to all supported branches.
