Vmstat reports no swapping of pages of ram to disk, so I don't think it would make sense to make it a Linux Swap drive.
I suppose I could move some actual tables and indexes to the device. Tablespaces might make this easy. I'm still using 7.4.3. If I had to pick between tables and indexes, which would make more sense to put on the solid-state device?
What would you do if you had a solid state hdd to use and you wanted to speed up PostgreSQL?
Depend what do you want obtain. Do you want speed up writes ? Are you annoyed by a full scan table that you can not avoid ? or what ?
