H2 does not recognize primitive array like double[] . If you render ST_Extrema as text, it is not readable. Morover you can't use ARRAY_GET on the returned value.

So what ? Could you explain a bit more ?

[nicolas-f]

The function should return Double[] or Object[] maybe in order to be recognized by H2 as an Array.
