BuildSwapped	crates/gravity/lowerv4/src/ops/hashjoin/build.rs	make_swapped	lifetime	-	join.buildside's swapped build keeps no partition bits	hash join	An inner hash join of two table scans where Gravity builds the hash table from the side PostgreSQL probes, because that side is smaller, keeps its whole hash table in memory where PostgreSQL would spill it to disk, so the statement fails with an out-of-memory error when the server has no more memory to give it.
