Hmm ... keep in mind that PostgreSQL is used as a base for a certain
number of commercial, non-BSD products (Greenplum, Netezza,
EnterpriseDB, Truviso, are the ones that come to mind).  Would this
exception allow for linking QuickLZ with them too?  It doesn't sound to
me like you're open to relicensing it under BSD, which puts us in an
uncomfortable position.
