Suggestion about tcp_keepalives_idle parameter in the document
there is the following description in the https://www.postgresql.org/docs/current/runtime-config-connection.html：
A value of 0 (the default) selects the operating system's default.-----but there is no description about“ the operating system's default value in the linux is tcp_keepalive_time kernel parameter”

Documenting the defaults for each supported operating system is not
PostgreSQL's task.
In this article[1]https://www.cybertec-postgresql.com/en/tcp-keepalive-for-a-better-postgresql-experience/#defaults, I figured out the defaults for Linux, MacOS
and Windows.
