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.
