Help me to chouse a simple (lightweight) solution to the master-slave replication of one table between two Postgresql databases. The table contains a large object.

Here you'll find a very good overview of the replication tools for PostgreSQL. Please, take a look and hopefully you'll be able to pick one.
Otherwise, if you need something really lightweight, you can do it yourself. You'll need a trigger and a couple of functions, a dblink module if you need almost immediate changes propagation, otherwise you can survive with cron.
