FUJITSU Enterprise Postgres 14では、width_bucket()関数でnumeric型を処理する場合、結果の誤差はないように変更します。
[例]
=# SELECT x, width_bucket(x::float8, 10, 100, 9) as flt, width_bucket(x::numeric, 10, 100, 9) as num FROM generate_series(0, 110, 10) x; x | flt | num -----+-----+----- 0 | 0 | 0 10 | 1 | 1 20 | 2 | 1 30 | 3 | 2 40 | 4 | 3 50 | 5 | 4 60 | 6 | 6 70 | 7 | 7 80 | 8 | 8 90 | 9 | 9 100 | 10 | 10 110 | 10 | 10 (12 rows)
