Sounds like a lot of work. I don't want to do anything risky. And they probably won't give me a ramdisk anyway. Being able to run a small but full featured, purely in-memory DB (sort of like SQLite) would probably fit a niche that Postgres competitors don't address. So I guess this is just a wish list / suggestion matter at this point. -dave -----Original Message----- From: pgsql-general-owner@xxxxxxxxxxxxxx [mailto:pgsql-general-owner@xxxxxxxxxxxxxx] On Behalf Of Michelle Konzack Sent: Saturday, November 17, 2007 11:48 AM To: pgsql-general@xxxxxxxxxxxxxx Subject: Re: Temporary, In-memory Postgres DB?

I have done this before but it requires very much memory if you need it writable and you must vaccmizer very often. You need a shellscript which replace the "startupscript" for the PostgreSQL in which you 1) create the RAMDISK 2) then decompress the previously build data.tar.bz2 3) start the PostgreSQL and replace the shutdownscript with your own shellscript which do 1) stop write access to the PostgreSQL 2) vacuumizer the database 3) shutdown the PostgreSQL 4) make a backup of the previously created data.tar.bz2 4) compress the datadir to data.tar.bz2 I run an Opteron 140 with 8 GByte of memory and sometimes I have problems with too less memory... but unfortunatly I have not found a Singel-Opteron Mainboard which support more then 8 GByte of memory where I prefere to use 16-32 GByte...
