Hi, This is just a small clarity improvement. tuplesort_performsort() skips sorting entirely when the result set has 0 or 1 tuples, but EXPLAIN still says it's using "quicksort". The patch changes that to "skipped"
For example: db=# explain analyze select * from now() order by 1; Sort (cost=0.02..0.03 rows=1 width=8) (actual time=0.126..0.126 rows=1 loops=1) Sort Key: now Sort Method: skipped Memory: 25kB -> Function Scan on now (cost=0.00..0.01 rows=1 width=8) (actual time=0.032..0.033 rows=1 loops=1) Patch attached. Regards, Marti
