This simple query reproduces the crash as well:
=# select json_object_agg(1, NULL::json);
json_object_agg
-----------------
{ "1" : null }
(1 row)
=# select jsonb_object_agg(1, NULL::jsonb);
server closed the connection unexpectedly
It happens that jsonb_object_agg_transfn is not able to manage
correctly NULL values in the context of a JSONB value, and it seems to
me that this is caused by an oversight in datum_to_jsonb regarding the
handling of NULL values.
Attached is a patch with some regression tests for master and
REL9_5_STABLE where the bug has been introduced.
Thoughts?
