It sounds like your system defines the TCP_KEEPALIVE symbol at compile
time but the kernel doesn't know it; maybe the package was compiled in a
system where the kernel does support that option, and you're running it
in one that doesn't?
Are you getting the message in the client side or server side? If the
latter, you should just set tcp_keepalives_idle to 0 in postgresql.conf.
If the former, I think the only option is to fix the libpq compile.
