hello, I use pgsql to store data for my program (hotel manager). The filesystem reports that the size on disk of database is not so bing (~100MB ~20MB actual data). I want to tune the engine to fit the database as much as possible in RAM, say: postgres, please, use 512MB (1GB) of my RAM just for your needs and load everithing on it. Is it possible and, of course, effective? Just taking a look to some tuning document I didn't find a direct answer (I'm not a smart guy) Thanks, Filippo
