Well, we replicate a 1 TB database between two locations. It is a

fairly active OLTP application, but certainly not pushing the limits

of what PostgreSQL can do in transactions per second.

Something that section 25 in the pgsql documentation is not clear about for hot-standby with WAL log shipping using the built-in streaming:

Can you choose which databases / tables on the master server get streamed to the hot-standby read-only server at the remote site?  If not, I suspect we'll have to go with either Slony or Bucardo.
