问题
Is there a way that I might query a database located on "Server 2" and get my data in "Server 1" ? That is return a set of records from a remote server to my local one.
PS: Not cross database query on same server because I know how to do that with dblink.
Update: great ty.
http://www.postgresonline.com/journal/index.php?/archives/44-Using-DbLink-to-access-other-PostgreSQL-Databases-and-Servers.html works like a charm. My bust was that I didn't see it on the dblink documentation on postgresql website.

Apparently dblink can be used to query other servers - Using DbLink to access other PostreSQL Databases and Servers

this is old - these days one would use the postgres_fdw module instead: https://www.postgresql.org/docs/9.3/static/postgres-fdw.html
