Description:

I'm getting absolutely misleading error message when trying to build a JSON
object from empty resultset.

Here is the simple code to reproduce:

select jsonb_object('{}'::text[], '{}'::text[])

Result of execution is

ERROR: unknown type of jsonb container
********** Error **********

ERROR: unknown type of jsonb container
SQL state: XX000

Expected result - jsonb object with no attributes, i.e.: '{}'
