Permissions required for service user account _after_ installation

The "Silent install of PostgreSQL on Windows" document states
that "The service user needs Log on as a service, Log on
locally and Access this computer from the network." If the
PostgreSQL database will only be accessed via localhost, are
these permissions still required after the installation has
finished (ie: are they required to simply run the database).
I hadn't seen this document until today and during my
installation script I take away the "log on locally" and
"access this computer from the network" rights after the
installation has finished, and so far everything seems to be
working properly. Or is just a matter of my not having
bumped into a problem yet?

For "log on locally", you are safe to remove it after the install. It'
sonly required for initdb.

I'm not 100% sure on the "access from the network". I seem to recall
there was a situation when it was needed by the general server, but I
can't remember what it was:-) And I'm not sure it was there.
