Hello, in my particular case I need to configure Postgres to handle only a few concurrent connections, but I need it to be blazingly fast, so I need it to cache everything possible. I've changed the config file and multiplied all memory-related values by 10, still Postgres uses only less than 50 Mb of my RAM.
I have 4 Gigs of RAM, how do I force Postgres to use a higher part of such memory in order to cache more indexes, queries and so on? Thanks!
