Hi all,
I have a large table that contains redundancies as per one field.
I am looking for a way to identify (or extract) a non redundant set of
rows ( _any_ one record per group) from this table and for each record
of this "distinct" set of rows, I would like to capture it's other
fields.

I've been using MySQL for years. I switched (er, mostly) to PostgreSQL
recently because I need to use PostGIS. It is all working now for the most
part, and PostGIS is absolutely wonderful.
I run CentOS 5.x and I do not like to upgrade vendor supplied packages. My

so if I switch target database from recovery mode to normal mode and do

Will it break the relationship between source and target? Do I need to

Yes. Just copy the files to multiple machines, the slaves are
completely independent.
