DB valid fields

[Stephen]

So I'm using freeradius with postgresql and eap-tls. I would love to
know where the documentation for the acceptable radreply entries is. The
closest thing to documentation that I've found has been:
https://wiki.freeradius.org/guide/SQL-HOWTO#populating-sql

Aside from the limited and anecdotal references found there to fields
like `Framed-IP-Address`, where can I find a comprehensive accounting of
the attributes and values I can leverage in my radreply table? 

Thanks in advance!
