Yeah. I gave a look to python but I don't want to add one more
language to the mix.
I enjoy strict type checking of plpgsql even if some bit of
syntactic sugar would help to make it more pleasing and I think it
is the most lightweight among the offer.
Still I don't know how easy it is with eg. python to load an array

familiar with the other PL languages I can't tell whether they
would be suitable in that respect, but I suspect Python or Java
would be able to handle this better.
Your suggestion about cursor could be the way... but I don't know
enough about cursors internals to understand if updating a field of
a cursor will cause disk writes.
I have not tried this, but the documentation says arrays can be
created for "any built-in or user-defined base type, enum type, or
composite type." So maybe you could define a composite type and stuff
those into a single array?
