Fwd: Data caching

От

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.

Cursors?

https://www.postgresql.org/docs/current/sql-declare.html

"A cursor created with WITH HOLD is closed when an explicit CLOSE 
command is issued on it, or the session ends. In the current 
implementation, the rows represented by a held cursor are copied into a 
temporary file or memory area so that they remain available for 
subsequent transactions."
