There is only one production and shipping replication that does not
require triggers that I know of and that is ours (Command Prompt).
It is also not a userland app but actually part of the PostgreSQL engine.

There is also ERServer which was first (?) but it tends to be a bit
of a beast to maintain.

There is Slony-I which is showing promise but is a Trigger based option.

Others include Peer Direct (Which I believe is query based) and 
PgCluster which is query based.

Each solution has pro's and cons. Slony-I for example appears to be 
better when doing mass updates or deletes than Replicator.

On the argument of significant features for 7.5:

Win32 Native
Nested Transactions
Background Writer....
