temporal_supportfn_ext() Datum temporal_supportfn_ext ( FunctionCallInfo  fcinfo, TemporalFamily  tempfamily  ) For functions that we want enhanced with spatial index lookups, add this support function to the SQL function definition, for example: CREATE OR REPLACE FUNCTION ever_eq(tfloat, float) RETURNS boolean AS 'MODULE_PATHNAME','temporal_ever_eq' SUPPORT temporal_supportfn LANGUAGE C IMMUTABLE STRICT PARALLEL SAFE; The function must also have an entry above in the IndexableFunctions array so that we know what index search strategy we want to apply.
