Looks like hierarchical queries are now officially stalled :(
Anyone want to take this up for 8.1?

Hi,
I haven't done any significant progress on that way because of lack of
free time.
Beside this, I'm recently changed my job and now I'm woking for MySQL.
I think it's not possible for me to continue work on PostgreSQL.
Feel free to take the patch and develop it further as long as you
mention me as author of initial version.
Regards, Evgen.
