[pgpool-hackers: 2696] Re: [pgpool-committers: 4513] pgpool: Set TCP_NODELAY and non blocking to frontend socket.

[Tatsuo Ishii]

It seems we forgot to set TCP_NODELAY option to frontend socket since
day 0. PostgreSQL always sets the flag, and we set the flag for
backend sockets, so I decided to set the flag to the frontend socket
because it's more consistent.

Best regards,
