Sir/Madam,

     I have two databases- db1  and db2
db1 is the master  and db2 is slave.

In db1,  create table t1(id integer  primary key);
In db2  , create table t1(id integer);

When i start replicating , why slony gives error cannot find index on id.
But in place of integer ,if i use int4 datatype, data is replicating properly.

How to solve the problem... Its urgent..

The schemas in the two database must be *identical*.  there are specific things you can let be different, but if you are just starting out, don't try to do that. also, there is a slony mailing list where the experts hang out.

Not entirely true.  You can have extra indexes on slaves etc.  But you
must have either primary key or unique indexes that match on both
ends.
