Hi. I wonder if there is such a thing or extension in the PG world. Here is my use case. I am using PG (PG10 to be more specific) in a cloud VM environment. The tables are stored in RAID0 managed SSD backed attached storage. Depending on the VM I am using, I usually have 256GB local SSD unused.
I wonder if PG could leverage this local SSD as a read (page/block) cache, to complement/extend the DRAM by used by shared_buffer today. Thanks.
