Yeah. The problem seems to be the ad-hoc (I'm being polite) code in
hstore_to_json_loose to decide whether a string should be treated as a
number. It does much more work than it needs to, and fails to have any
tight connection to the JSON syntax rules for numbers.
Offhand, it seems like the nicest fix would be if the core json code
exposed a function that would say whether a string matches the JSON
number syntax. Does that functionality already exist someplace,
or is it too deeply buried in the JSON parser guts?
