Are you using the extended query protocol?  If so you probably have
forgotten the need for a Sync message.  After an error, the server
discards frontend messages until it sees a Sync.  This is needed so that
you can fire off several component messages in an extended-query
operation without waiting to see whether each one succeeds.  You put the
Sync at the point where you want to wait for results.
