Hi all,
I'm just trying to give middlegen a spin.
Example worked fine with hsql, but when I tried
to connect to real postgres database I got following
error:
--%<------------------
[middlegen] (middlegen.MiddlegenPopulator 235 )
ERROR: Unable to identify an ordering operator '<'
for type 'bytea'
[middlegen] Use an explicit ordering operator or
modify the query

Postgres is 7.1.3, Middlegen - just downloaded from
SF,
I'm using driver supplied with middlegen.
Can somebody point me in the right direction?
