where to add/change commands - Mailing list pgsql-hackers

Hi folks

I am trying to make CLUSTER command just a bit verbose,as an option  
here. Added bits to gram.y that should support CLUSTER [VERBOSE] ...  
but psql doesn't seem to pick it up.
Where else do I need to update it, besides gram.y, cluster.c and of  
course adding new field to ClusterStmt.
I tried seaching the list for such hints, but didn't found anything  
usefull.

thanks.
