postgresql 9.5.4 with ssl commented out

On this particular server that postgresql 9.5.4 is installed, I comment out
ssl=true and for some reason a bunch of child processes start up for the
main postgresql process. When I uncomment it, the child processes go
away. There were no connections into the database except for myself. Any
idea where these child processes are coming from?
