tcp_keepalives_idle
Hi,
I am struggling to understand what following phrase says:
tcp_keepalives_idle (integer)
Specifies the number of seconds before sending a keepalive packet
on an otherwise idle connection.
What I am not sure is the meaning of "otherwise". Can I safely replace
it to:
Specifies the number of seconds before sending a keepalive packet
on an other side of idle connection.
What I try to want to mean here is, "other side" is frontend side
connection point.
Or I am completely misunderstanding?

It means "the connection is idle except for keepalive packets".
We could perhaps just drop the word "otherwise", if people find
it confusing.

No, that's not a good fix.

Wah. I seemed to completely misunderstand what the pharase
says. Thanks for clarification. I agree to drop "otherwise".

Sure. I was absolutely misunderstood.

I had some problem interpreting these explanations as well:
/messages/by-id/527A21F1.2000408@joh.to
Compare that to the description in the libpq documentation: "Controls
the number of seconds of inactivity after which TCP should send a
keepalive message to the server.".

Good point. I have improved the server-side keepalive parameter
descriptions to use the superior libpq text, with adjustment.
Applied patch attached.
