Database.HDBC Idle Connections

Hello, does anyone have production experience with Database.HDBC Postgres with regards to idle connections?

For example, if I setup a single “server-to-database” connection using connectPostgreSQL. If this connection becomes idle for some hours or days, will it be disconnected automatically or the server still can use this connection to query database? Because I have not found any information about that.

Update: those connections seems to be persistent. Tested with a couple of hours of being idle.
