PG 12 hstore creation cast issue

We have this kind of code that worked in 9.6:

select hstore(array['foo'], array[1.0::numeric]);

But now yields:

ERROR:  function hstore(text[], numeric[]) does not exist
LINE 1: select hstore(array['foo'], array[1.0::numeric]);
               ^
HINT:  No function matches the given name and argument types. You might
need to add explicit type casts.

Is there a way to create hstores with numeric types as data? Does
everything need to be cast as text?
