H3_POLYFILL returns empty list at some H3 resolutions for the same geometry (Postgres)

[bkanuka]

I have a come across a couple times when H3_POLYFILL does not produce results. For example:

SELECT carto.H3_POLYFILL(ST_Transform(ST_TileEnvelope(1, 0, 0), 4326), 2, 'center');  -- empty

however, the same geometry works with different H3 resolutions. For example, these 2 produce valid results:

SELECT carto.H3_POLYFILL(ST_Transform(ST_TileEnvelope(1, 0, 0), 4326), 1, 'center'); -- valid
SELECT carto.H3_POLYFILL(ST_Transform(ST_TileEnvelope(1, 0, 0), 4326), 3, 'center'); -- valid
