After following your link, I am sure that some RCS systems that use MySQL
as a backend *may* use UDFs as part of their persistence logic, but those
would be specific to the RCS product you are curious about. There aren't
any "generic" UDFs that will apply to all verson contol front-ends. Does
the one in the link use any UDFs? I couldn't tell from what I read and to
be perfectly honest, I couldn't figure out from the reading that RCS
actually used MySQL at all.
Is this what you wanted to know or have I still missed something vital to
the question? It's been one of those days for me.

RCS does not use MySQL or any other SQL engine.
I am looking to use a SQL backend for RCS.
RCS is a specific tool unlike source control management (SCM), it is a
text file database. There are no SQL based RCS implimentations that I know
of, that was why I asked in the first place.
A RCS file is comprised of:
meta data bout the state of the file
current source
0..N reverse deltas from current source
meta data about the various revisions represented,
including who, when, why.
