+ <h1>PostgreSQL notes</h1>
+<p>
+PostgreSQL ships by default with a maximum of 31 character column names. If
+you use arbitrary RADIUS attributes longer than 9 characters, fs-setup will
+fail with `duplicate column' errors (in the part_svc table).
+Solution: use a different database
+engine, or recompile PostgreSQL with 64 character column names.
+</p>
+Future versions of Freeside will keep all column names under 31 characters to
+avoid this problem.
+</p>
+<p>
+( I've personally been unable to get PostgreSQL working with larger column names,
+though the process does look like it should be straightforward. If anyone is
+interested in assisting me with this, please get in touch.
