Hi, We are currently working on cstore extension. We are storing the all the inserts in a shared memory and then flushing the tuples to the database. We are using a background worker to periodically flush the data. But the problem is we are not able to do the insert the data during the periodic check. I get the following error. "ERROR: cache lookup failed for foreign table 33321" Is there any possible ways to make this possible. And also before shutting down the postgres I have to flush the data to the database. I try to call the fdw routine that is used to flush the data to database. But I get an error again saying "FATAL: invalid cache ID: 31".
