That's the old SQL operator (which is not even there anymore) that's
equivalent to the hstore(text,text) constructor function, ie
"text => text returning hstore". It's quite a different concept
from the => notation inside an hstore literal. That is:
'foo'::text => 'bar'::text
is not like
'"foo" => "bar"'::hstore
even though they have the same end result.
