write a daemon config file by using stored procedures!

Hi!

I’m new in Postgres,

Is there a way to start postgres as user root, yes this isn’t the normal way, but I will use it only for my own,

Or is there a other way to write with a stored procedure a file, to a directory where user postgres haven’t access, becourse I will create a config file for a daemon, and restart it in the next step,

Thanks for help
