Thread: Parallel pg_dump/restore and LOs

Hi all.

 

When dumping large-objects it doesn't appear that it's done in parallel, meaning only one thread for dumping all LOs. Is this the case?

When pg_dump comes to dumping large-objects it outputs (when -v is specified):

pg_dump: saving large objects
Then it seems only 1 CPU is working.

 

Are there some plans to make dumping large tables (typically LOs) benefit from parallelism?

 

Thanks.
