非互換
EXPLAIN (BUFFERS)を実行した場合の表示を変更し、“shared/local”と表示されていたところを“shared”に変更します。
postgres=# set track_io_timing = on; SET postgres=# explain (buffers) select * from pg_proc; QUERY PLAN --------------------------------------------------------------- Seq Scan on pg_proc (cost=0.00..132.47 rows=3347 width=2003) Planning: Buffers: shared hit=93 read=7 I/O Timings: shared/local read=1.288 (4 row)
postgres=# set track_io_timing = on; SET postgres=# explain (buffers) select * from pg_proc; QUERY PLAN --------------------------------------------------------------- Seq Scan on pg_proc (cost=0.00..136.15 rows=3415 width=1983) Planning: Buffers: shared hit=142 read=18 I/O Timings: shared read=1.125 (4 row)
