Hi Amit,

Here is a statement that seems to gobble up all memory and to totally 
lock up the machine. No ctrl-C - only a power reset gets me out of that. 
It was in one of my tests, so it used to work:

select json_query(
     jsonb '"[3,4]"'
   , '$[*]' returning bigint[] empty object on error
);

Can you have a look?

Thanks,

Erik
