This is due using anycompatiblearray for the left operand in @>>.
To solve this problem we need to use @>>(anyarray,anyelement) or introduce
a new opclass for gin indices.
These are the two approaches that come to mind to solve this. Which one is
the right way or is there another solution I am not aware of?
That’s why I’m asking this on the mailing list, to get the community’s
input.
