Hello

Is there a postgres extension or project related to
application-level/foreign-table data caching ? The postgres_fdw extension
fetches data from foreign table for each command.

I have seen previous messages in archive about caching in form of global
temp tables, query cache etc. There are good discussions about
whether support should be built-in but did not find any implementation.

I have seen the 44 postgres extensions that come pre-installed with ubuntu
16.04 but none of them do this.

Thanks.
Anant.
