what is the best way to access cold data on another server?
Hello everyone;
In addition to the actively used data, there are other data that are
very little accessed. I want to separate the less used data to save space
and reduce maintenance operations. I want to use a separate postgres
instance for this. Now the question is; How do I link these two instances?
postgres_fdw or dblink? or what other solution? Which one would be better?
thanks in advance..
dblink is outdated, postgres_fdw is current.

I am concerned about the security of fdw. so I actually asked for its
comparison with dblink and wondered if there was any other technique to do
this.

Foreign Data Wrapper is a good option, and yes, it is secure.
Another option would be to store these data as CSV files and use file_fdw
to define them as "external tables".

dblink may not be getting lots of improvements, but it is maintained to the
same standards as postgres_fdw is. FDW inhibits parallel queries, on both
sides. dblink maintains that possibility, (while tedious to do in a
useful way). Also, FDW cannot push UDF calls, while dblink can if you
manually write them into the sent query.
