-- Aggregates of bit-sliced columns over a partitioned table that plan-time
-- pruning leaves ONE leaf of (DESIGN.md §52.13, §16, "A parent pruned to one
-- leaf"): the cases of slices_partitioned.sql that prune to a single leaf,
-- through a sub-partitioned parent, to an empty leaf, to the NULL partition
-- of a LIST and to one leaf of a HASH.
--
-- PostgreSQL 18.0 to 18.6 lose a disabled path's disabled_nodes in an
-- Append of one child (fixed upstream in 18.7, "Propagate disabled_nodes to
-- single-child Append paths"), so the ordinary plan the checks below
-- disable is not disabled there, and it wins on cost against the slices on
-- data this small.  The test stops at once there, and on builds of the 18
-- branch stamped 18.6 that have the fix, which the version cannot tell
-- apart (slices_partitioned_leaf_1.out).
