Обсуждение: Question regarding coopting Database Engine

Hello,

I'd like to know if its possible to coopt the postgres storage subsystem to
rely entirely on ram based structures, rather than disk. Any documentation
or ideas would be appreciated.

Cheers,

Steve

Sure, create a ram disk.  Set $PGDATA to it with proper permissions, 
initdb, and restore.

Not sure why'd you wanna do it, as any crash loses all data, and 
postgresql's strengths lie in its ability to survive the most brutal power 
off situations mid-transaction etc...

Just so you know, this isn't going to make the system any faster.

I assume you are trying to do something like put the database onto a
bootable CD that fires up some static application with static
information?

Hi Steve ,

I m interested on similar things but I m too new to PostgreSQL  to give any hint .
My first approach is to compile with a different compiler to get a idea of the system.

Best regards

Why don't you just define a RAM disk and run PostgreSQL on it? ;)
