Oh, Thank you for teaching.
I add a function pq_gettcpusertimeout() same as keepalives*.

Same as backend-side, I made keepalives documentation reference.
I refered keepalives* documentation and modified my doc.

Thank you for your point!
Removed in both patches.

Sorry, my coding was bad...
I integrated it with coding about keepalives.

Moved!

This is also my bad coding...
Removed!
