I have not jet been reading all of it but some of the README files. I
will keep that hint in mind but first of all I'll read something about
bitmap compression and other relevant techniques before starting to
discover the index internals of postgresql... ;-) I've been using all
kinds of functions in oracle for a long time but never had the
experience to implement any indexing strategies. The only thing I did
were some operating system extensions for minix during my os-studies
(scheduling, driver, acl etc.)

If there is anything additional/special to know further, I apreciate any
hints.

Regards and thanks,
Yann
