*Updates till now:*
- added a record to pg_proc (src/include/catalog/pg_proc.h)
- modified opr_sanity regression check expected results
- implemented a low-level function called `array_contains_elem` as an
equivalent to `array_contain_compare` but accepts anyelement instead of
anyarray as the right operand. This is more efficient than constructing an
array and then immediately deconstructing it.
*Questions:*
- I'd like to check that anyelem and anyarray have the same element
type. but anyelem is obtained from PG_FUNCTION_ARGS as a Datum. How can
I make such a check?
Best Regards,
Mark Rofail
