It looks to me like there's support for setting KEEPIDLE and KEEPINTVL via sysctl, but of course that's system-wide and presumably requires root privilege to set. (Apple seems to have inherited that from various BSDen, btw; it's not unique to Darwin.) > #define TCP_KEEPALIVE 0x10 /* idle time used when > SO_KEEPALIVE is enabled */ > Should we try to support that as a synonym for TCP_KEEPIDLE, if that's > what it is? Or not worry about it? Or... what? Yeah, a bit of rooting around in the Darwin sources shows that this value is used as a per-connection override for tcp_keepidle. So it is a synonym. Not sure if it's worth supporting when the other value can't be set too. Maybe it'd be more useful to document that people can set the system-wide values if they're desperate. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
