…to 59ba0ad59c Wire `tfloat_sin`, `tfloat_cos`, `tfloat_tan` from MEOS as `sin(tfloat)`, `cos(tfloat)`, `tan(tfloat)` DuckDB scalar overloads, following the same `TemporalUnary` pattern as `exp`/`ln`/`log10`. The pin advances from `278863520b` to `59ba0ad59c` (tag `ecosystem-pin-2026-06-11a`), which adds these three trig kernels and the `ensure_srid_reconcile` helper.
Expose eDwithinPairs, tDwithinPairs and aDisjointPairs as set-returning functions and minDistance(arr, arr) as a scalar reduction over tgeompoint[] and tgeometry[], wrapping the MEOS edwithin_tgeoarr_tgeoarr / tdwithin_tgeoarr_tgeoarr / adisjoint_tgeoarr_tgeoarr / mindistance_tgeoarr_tgeoarr kernel. The Pairs functions return the qualifying (i, j) index pairs into the input arrays; tDwithinPairs also returns the per-pair tstzspanset of when the within-distance relationship holds; minDistance returns the exact set-set spatial minimum distance.

Expose eDwithinPairs, tDwithinPairs and aDisjointPairs as set-returning functions over tgeompoint[] and tgeometry[], wrapping the MEOS edwithin_tgeoarr_tgeoarr / tdwithin_tgeoarr_tgeoarr / adisjoint_tgeoarr_tgeoarr kernel. Each returns the qualifying (i, j) index pairs into the input arrays (1-based, matching DuckDB list indexing); tDwithinPairs also returns the per-pair tstzspanset of when the within-distance relationship holds. Stacks on the pinned-MEOS foundation that carries the kernel symbols.
