Most Reliable Replication Method

Hi there,

Can I get opinions/recommendations/etc on the most reliable (ie
semi-enterprise at least) replication product/solution/whatever for
Postgresql? I have no experience with replication on this database
platform and frankly some of the packages which offer it seem a little
'dodgy' (not speaking from knowledge, just most of them don't appear
to be very finished or polished). I LIKE Postgresql as a database
platform and find it regrettable that it is missing a feature so
necessary for installing it in the enterprise.

Any testimonials/recommendations/opinions etc would be greatly
appreciated.
