Re: [RFC][PATCH]: CRC32 is limiting at COPY/CTAS/INSERT ... SELECT + speeding it up

Hi,

This thread died after me not implementing a new version and some potential 
license problems.

I still think its worthwile (and I used it in production for some time) so I 
would like to implement a version fit for the next commitfest.

The code where I started out from is under the zlib license - which is to my 
knowledge compatible with PGs licence. Whats the position of HACKERS there? 
There already is some separately licenced code around and were already linking 
to zlib licenced code...

For simplicitly I asked Mark Adler (the original Copyright Owner) if he would 
be willing to relicence - he is not.

For anybody not hording all old mail like me here is a link to the archives 
about my old patch:
