[Pgpool-general] "kind does not match"

[Bill Moran]

googles on this have turned up nothing.

I'm running two instances of PostgreSQL 8.1.4 on the same machine 
(different ports) for evaluation purposes.  pgpool seems to be starting
fine, but I can't connect with psql:
# psql -U pgsql -h 127.0.0.1 -p 9999 template1
psql: server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.

Running pgpool with -nd reveals the following error when I try to
connect:
2006-10-18 11:40:03 DEBUG: pid 55189: I am 55189 accept fd 6
2006-10-18 11:40:03 DEBUG: pid 55189: Protocol Major: 1234 Minor: 5679 database:  user:

2006-10-18 11:40:03 ERROR: pid 55189: read_kind: kind does not match between backends master(82) secondary(69)

What does that mean?  Do I need to provide config files or any more
information?
