3. Like 1 but with the use of a connection pooler like pgpool. Not sure
if pgpool supports asynchronous queries, but that would help as well by
pulling data from the 13 databases in parallel instead of serial: get
the queries onto the 13 servers without waiting for results, then as
soon as data is ready, get results and display.
