Attached is a bit of perl to generate regexes to identify TLDs, 2LDs,
3LDs, and 4LDs from a recent (3.x) version of Mail::SpamAssassin.

The results should be PCRE-compatible so you should be able to use them
without perl. I originally used this script to generate code for a PHP
application to create DNSBLs from web probes, attacks, and blog spam but
it should be applicable to mod_log_sql as well.

Basically, if you match an xLD (top, second, third, fourth-level
domain), /(([^.]+\.)(xLD))$/ should match the base domain where you'd
store the log entry. www.example.co.uk and example.co.uk would match the
2LD '.co.uk' giving a base domain of example.co.uk for both. Similarly,
www.example.austin.ci.tx.us and example.austin.ci.tx.us would end up
under austin.ci.tx.us.
