pq slaves have special buffers in the large pool.

I do not believe, however, that this is the ONLY place they read from.

Perhaps a Latvian web site has more details?

|| Hi,
|| Is it true that when running parallel query, the parallel
|| query slaves do
|| not read from buffer cache even though the data resides in
|| the buffer cache
|| ie the slaves read directly from disk.
||
|| Does not make sense to me. Can someone clarify that?
||
|| Thanks.
