Ok, that'l teach me to use beta software.  Now that I've tried my process
with 1.0.5, my database seems to be syncing.

Subject: [Slony1-general] Slony crash during activation of mirror --
myfault?


 
First, sorry if this is either an FAQ or a common problem.  I've been using
Postgres for quite a while, but this is the first week I've been using
Slony.
 
I'm trying to replicate a database:
Master: PostgreSQL 8.0.1 on i686-pc-linux-gnu, compiled by GCC gcc (GCC)
3.2.3 20030502 (Red Hat Linux 3.2.3-42)
Slave:PostgreSQL 8.0.0 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.3
20030502 (Red Hat Linux 3.2.3-49)
Slony: slony1-1.1.0.beta4

I created a trivial example of a single table replicating to another and
tested that.  Now I'm using a copy of a production database.  I've written
the little slonik scripts that initialize the cluster, create the tableset,
etc...

I can fire up slon, and then when I actually subscribe the slave to the set,
the slave's slon crashes.  It seems to be trying to drop a constraint, but
specifying an index.  This happens for at least two tables (I commented one
out of the tableset and tried to get past it).

Here's some output:
