Hello

I found http://mirror.fslutd.org/postgresql/projects/pgFoundry/hashdistinct/pg-hashdistinct.diff
project. Is this project living?

Have somebody plan work on it?

Regards
Pavel Stehule

This was a SoC project from a couple years ago.  It probably wouldn't
take too much to get it merged back into the codebase.  IIRC, the only
thing it lacked was more optimal optimizer code.

I don't think so.

ok I'll plan look on it - I am thinking about rollup implementation
and hash distinct would be intrduction to some new parts of pg for me.
