[Dovecot] pop-before-smtp in SQL?

I need pop-before-smtp (let's not discuss the advisability of the method), but I'm annoyed at the inefficiency of the classical perl script that parses the logs.

A long time ago I modified the perl to add the tuple (IP, time) to an SQL table that the MTA looks at, and to clean up periodically. I found that this was the best way to deal with multiple servers that have to share an SQL database anyway.

Wouldn't it be quite trivial to make dovecot write to an SQL table upon sucessful login, instead of all this log file parsing by an additional daemon?
