Обсуждение: pooler/router?

Hi all,

I have a customer who needs to split a set of pg databases that have
outgrown any possible "big iron" and needs to do it quick, at zero
impact on lots of existing and basically undocumented applications.

I was wondering whether there is anything I can drop in as a
"middleware", that will get any incoming connections to oldserver:5432
and reroute them to a set of individual boxes, based on the targeted
database. PgPooler + routing, sort of.

Any hint is greatly appreciated.
Cheers
Bèrto

 With pgbouncer you can create virtual databases and map them on
 different hosts. It is very light and open source:
