Hello, My programm uses postgres every minute, thats why i keep connection to postgres all the time my programm live. When the programm just started postmaster gets about one meg. But in few days after the postmaster process grow up to 15 Mb in memory, thow my databases are small enough (approx 1 meg). How can i explain that? Postgres6.4 on BSDI 3.1 Thank you. --------------------------- Sergei Chernev Internet: [EMAIL PROTECTED] Phone: +7-3832-397354
