Version/Change Management of functions?

[Michael Loftis <mloftis@xxxxxxxxx>]

OK I know this is an odd question but I'm working on an app that will rely 
more and more on database driven functions, and while the app's source is 
in SVN, and I intend for the source of the SQL scripts to also be there, I 
was wondering...what are people doing for version control and change 
management on their custom (esp PL/pgSQL and say PL/Perl) functions?
