Re: Configuring postmaster to use all available memory

Hi Joe,

Have you looked into tuning the postgresql.conf file?

It's the one in the PostgreSQL data directory. The exact settings
needed depend on your situation, but by taking some time you'll be able
to figure out decent values.

Bruce Momjian has written a document that goes into the theory behind
it, and gives good ideas:

http://www.postgresql.org/docs/aw_pgsql_book/hw_performance/

Also, there is a lot of discussion about this on the PostgreSQL
"Performance" mailing list so it would be useful to check through the
mailing list archives for this.

Hope that helps.

Regards and best wishes,

Justin Clift
