Hello, I have the following problem:
When I run some query after I just run the Postmaster, it takse several seconds to execute (sometimes more than 10), if I rerun it again afterwards, it takes mere milliseconds. So, I guess it has to do with PostgreSQL caching.. But how exactly does it work? What does it cache? And how can I control it? I would like to load selected information in the memory before a user runs the query. Can I do it somehow? As PostgreSQL is used in my case as webserver, it isn't really helping if the user has to wait 10 seconds every time he goes to a new page (even if refreshing the page would be really quick, sine Postgre already loaded the data to memory). P.S If the query or its EXPLAIN are critical for a better understanding, let me know.
