I'm trying to set up Postgres replication via rserv, but at this time
I'm forced to do so in an unusual fashion. Our production server is
running Postgres 7.1.3, and our development server is running Postgres
7.4. The production server is going to be migrated to 7.4 fairly soon,
but not right away. The development server (7.4) is going to become the
production server later today. When that happens we're going to want
(for the short term, anyway) to use the former production server (7.1.3)
as a database backup.
Therefor, what I'm trying to do is replicate from a 7.4 server to 7.1.3.
I've got rserv set up currently on the 7.1.3 machine. Below are the
steps I've taken. Note that the 7.1.3 machine is at 192.168.1.5 and the
7.4 machine is at 192.168.1.12, and the script is running on the 7.1.3
machine:

Replicate --masterhost=192.168.1.12 --masteruser=dan
--masterpassword=<password> yp yp
<error occurred here>
Replicate --masterhost=192.168.1.12 --masteruser=dan
--masterpassword=<password> --slaveuser=postgres yp yp
<error occurred here>
The error that occurs is a very informative:
>>>>>>>>>>>>> ERROR: -1
I've added some debug text to the Replicate script that shows me this
message is coming from the call to PrepareSnapshot.
Any suggestions on what might be causing this error?
