Folks,
I'd like to see about getting an enhanced UNNEST, first the one
according to the SQL standard, namely with an optional WITH ORDINALITY
clause, and possibly some extra enhancements.
In order to get WITH ORDINALITY, would it be better to change gram.y
to account for both WITH ORDINALITY and without, or just for the WITH
ORDINALITY case?
Also, there's been some enthusiasm for a different kind of enhancement
of UNNEST, which would go something like this:
UNNEST(anyarray, number_of_dimensions_to_unnest)
That'd probably be a separate patch, though.
Cheers,
David.
