Just FYI:
Andrew Dunstan pushed:
- Correct volatility markings of a few json functions. json_agg and
json_object_agg and their associated transition functions should
have been marked as stable rather than immutable, as they call IO
functions indirectly. Changing this probably isn't going to make
much difference, as you can't use an aggregate function in an index
expression, but we should be correct nevertheless. json_object, on
the other hand, should be marked immutable rather than stable, as it
does not call IO functions. As discussed on -hackers, this change
is being made without bumping the catalog version, as we don't want
to do that at this stage of the cycle, and the changes are very
unlikely to affect anyone.

So it's not like it can't happen.
