Best way to replicate a DB between two servers (master/slave)

Hello everybody,
I know there was an announcement on www.postgresql.com, that sometime in the
future there will be a sort of replication mechanism for PostgreSQL.

Now the problem:

I have two servers, one providing content for a website (using PHP),
anotherone where users are editing the contents. I now have to update the
content-server on a regular base with the changes made in the
editing-server. I thought of dumping the whole database through ssh to a new
database on the content-server, then drop the old one and rename the new one.
I guess the content to sth. around 5MB, so having a 5Mbit leased line,
network traffic should be no problem.

I see I will run into problems, when an old postgres-process is still
connected to the database. Alternatively I thought of creating a
modification timestamp for every recordset involved and pumping only the
modificated sets to the content-server. I already have triggers running for
providing information about updated/inserted recordsets. But what about
deleted ones? I guess best would be to collect information about these in a
seperate table and delete the ones on the content-server based on this table.

Does anyone know of a more sensible way to get replication?

Best Regards
Mirko
