Taking the risk of running offtopic: That value is defined in Solaris as well. Use: ndd -get /dev/tcp tcp_keepalive_interval to retrieve it, and /usr/sbin/ndd -set /dev/tcp tcp_keepalive_interval 3600000 to set it to one hour. Check http://sunsolve.sun.com/search/document.do?assetkey=1-30-2876-1 for more information. Regarding the possibility of heartbeats in postgres ... have no idea how wise would it be ... there's people more qualified here that could answer that ;-D Hope this helps, anyway. Regards.
