Also, it's going to be a fairly rare app that will need to both
look at the current logfile and access the database, so providing
visibility via a sql function seem clunky.

Maybe just have the logger maintain a symlink to the current
logfile, or log to a static filename and only use a dynamically
generated filename when renaming the log file during rotation?
