Hello,
I need to union three PostgreSQL tables and this won’t be a problem but the tables are on different servers. Basically, I have an administrative server that needs the tables viewable in a web administrator and three query servers that log the needed data locally. Is there a way I can do this without using Slony-I to replicate the data to the administrative server?
