erserver 1.2 problem

P: n/a

Downloaded the eRServer 1.2 source (thanks, guys) and installed, and am
having a problem. Anyone else dug into this yet?

Situation:

PG 7.3.4 on linux (master)
Its been tried with 3 slaves, all 7.3.4, 2 on OS X and one on Linux.

It builds fine. It installs fine. I go through the setup with no
problems (calling createlang, doing the initial ers_setup, adding
tables, adding slaves, etc.)

The startup goes fine. No complaints in the log file. It sees every
slave.

Problem is, nothing seems to replicate. I insert records into the
tables on the master and nothing happens. If I am reading the logs
right, it thinks it is:

I tried setting it to output more debug messages by setting
'debug=true' in replication.conf, but it doesn't seem to add any more
to the logs.

The _rserv_slave_sync_ tables seem to have activity, but the
_rserv_slave_tables_ table is empty.
If my wife was standing behind me, I would expect she would say 'Its
right in front of you, dear', but I can't seem to figure out the
problem. Anyone else playing with this yet that can shed some light?

P: n/a

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.
