[HACKERS] Json support for array pseudotypes

From
Andrew Dunstan
Date:
The attached tiny patch lets the to_json(b) routines convert objects
with array pseudotypes to json{b}. The main impetus for this came from
my trying to convert the annyarray columns in pg_stats to json and
finding that they ended up as text instead of json arrays. This way
to_json on these columns does what is expected.


cheers

Looks reasonable offhand, but maybe you should add some test cases?

Yeah, I will. Not sure how to add a test for the RECORDARRAYOID case. We
don't seem to have any of those hanging around.
