Hello,

O.k. something is not right. Could you please post a request
to support@commandprompt.com with the following information:

1. master postgresql.conf replication configuration, we don't
need the whole postgresql.conf
2. slave postgresql.conf replication configuration, we don't need
the whole postgresql.conf
3. The schema of the table you are inserting into
4. The schema of the table that is supposed to be recieving the updates.

Thanks.
