They are all slaves, created from several primary db servers. These slave servers do not need to communicate with each other. But I need to allow people to connect to these slave servers. Giving out let's say 50 different ip and 50 different port to users is really inconvenient, that's where pgbouncer helps. It acts as a proxy. I can not use pgbouncer since it does not support ldap with TLS or SSL.

>> Re: handling multiple connection.
>> I have about 50 db instances running on each separate port on several boxes. Right now we just give one port to user, which is 6432, that's the port pgbouncer listens on. Then pgbouncer routes the connection to a different port/host based on the name of the db provided. This can be mapped in pgbouncer config file. The benefits of This mapping is end user do not need to know port/host of each db. I would like to know if pgpool can do the sames.
