The platypus model he has has an external PSU. The external PSU can be
easily plugged into an UPS. Thus if the main system is shut down as long
as the UPS lives and/or there is power otherwise to the external PSU, the
card will keep the data.

I read from his post that the Platypus RAM disk _is_ his reliable
storage, just with some peculiar characteristics, like big transfer
speeds and uniform sup

The idea of a RAM disk based database and reliable storage are in
complete opposition. Forget it.
The question is: What do you need the *raw* speed of a RAM disk for, and
what can you tollerate for overhead for reliability?
You have posed a question about how to implement a flawed solution, wha

This is the drawback to RAM drives, period. If there was some way to use a
RAM drive without risking your data, everyone would do it (or at l

that still requires you to have your xlog on hard drive)

First suggestion: upgrade to 7.2.4 to address several bugs.

Hello,
I need some insight on the best way to use a RAM drive in a Postgresql
installation. Here is our situation and current setup:
Postgresql 7.2.1
Dual PIII 800
RAID 5 SCSI disks
Platypus 8GB PCI QikDrive (the RAM drive). http://www.platypus.net
The Platypus RAM drive is a PCI card with 8G
