Creating Synonym For a Table in PostgreSQL over dblink?

Question

I have two PostgreSQL databases connected over dblink extension. I want to create synonym for a table in first database so the queries that are coming through application I can route them to the table in the second database. It will be good to mention that both databases has the same structure.

Is it possible to create a synonym or is there any alternative way to do so?

Answer 1

That's exactly what foreign data wrappers and foreign tables were created for:

You create a foreign server pointing to the source server, and then a foreign table that enables access to that remote server.

Some examples for that are in the description of the Postgres foreign data wrapper:
