Conn. loose at some places | TCP keepalive

Hello!

At home me and some other colleagues loose the connection after 5 minutes.
In other places (office) this not happens.

I wrote about this here:

Yesterday I found a solution-like thing for PGAdmin III here:
https://superuser.com/questions/729034/any-way-to-keep-connection-alive-in-pgadmin-without-setting-it-on-the-server

In PgAdmin IV I also have this problem.

But here I don't find same "service" option to link to my parameters.

What I can do here? Do you know hidden service option in PGAdmin IV?

The solution is may be an option for "SQL command list after connect" for
each servers - with this I could configure TCP keepalive parameters
manually.

Thank you for your answer!
