Re: erserver 1.2 problem

It appears in my case that the ers_addtable is failing to add
everything it needs to the slave tables, with a:

DBD::Pg::st execute failed: execute on disconnected handle at
/db/erserver/lib/eRServer.pm line 54, <IN> line 22.

which is the point it actually tries to add stuff to the slave. I'm not
a perl head, so I'm not sure at the moment how to fix the problem.
