MergeRunPulled	crates/gravity/lowerv4/src/face/slot_run.rs	make_end	lifetime	-	a merge inner run filled as its merge reads it grows in place	merge join	A merge join whose inner side Gravity reads one row at a time as the join asks (and a sorted INTERSECT or EXCEPT reading its right input that way) keeps every row it has read in memory where PostgreSQL's Materialize spills to disk and drops rows behind the merge, so the statement fails with an out-of-memory error when the server has no more memory to give it.
