I think you took Tom's comments the wrong way. He is suggesting you
are nuts to attempt trigger based data transfer to remote server when
there are two clearly better options, slony and dblink. You took as a
personal insult which was just some frank (and frankly good) advice...
Slony is in fact the _solution_ to the problem of transferring data
between servers with triggers. If your tables are well designed and
you are reasonably proficient with stored procedures, and you
requirements of transfer are very specific and not extremely time
sensitive, a poll based system over dblink is also a good solution.

based on this you may want to rig dblink/poll. 3rd option is pitr
shipping to warm standby, depending on your requirements.

now that's a bit dramatic :-)
