Hello, I have a hopefully simple question. I've found documentation about the meanings of the various variables in postgres.conf -- if it comes to memory consumption and buffer size. I've also found hints as to making them too large decreases performance. But -- how can I measure how well the current settings fit? Are there tables to watch on how quickly things like temp tables get written out to disk vs. being held in memory? We'd like to find an appropriate size for our database, but can't even yet say if we're in the right ballpark on a machine that has RAM to spare still. What can I look into?
What version of postgres are you using? 8.3 (currently in beta) has facilities for tracking temp file creation.
