Hi there!
I want to propose the patch for adding the hierarchical queries posibility.
It allows to construct queries a la Oracle for ex:
SELECT a,b FROM t CONNECT BY a PRIOR b START WITH cond;B
I've seen this type of queries often made by adding a new type, which stores
position of row in the tree. But sorting such tree are very tricky (i think).
Patch allows result tree to be sorted, i.e. subnodes of each node will be
sorted by ORDER BY clause.
with regards, evgen
