Hugues: thank a lot for your fix.

The function now runs without error... but it's been running for almost an
hour now :(

Compared to the 30-ish seconds it takes using the hard-coded query, and the
some 120 seconds using the PLV8 version, I cannot think of using the PLPGSQL
version in its current formulation. 

Does anyone else has a possibly faster suggestion, more in the ballpark of
the two other methods?

Thanks,

G
