Keep in mind that pcre has an advertising clause in its license
(software that distributes pcre commercially or non-commercially needs
to add a note to the effect in its documentation / online help). Since
PostgreSQL's license doesn't have this restriction, it would be shame to
impose that requirement on PostgreSQL users.

(Note that as I'm not a lawyer, my interpretation of the license may not
be correct.)

Agreed -- ISTM that Spencer's new engine is probably the best choice.
