Обсуждение: pgsql: Fix initialization of pg_stat_get_lastscan()
Fix initialization of pg_stat_get_lastscan() A NULL result should be reported when a stats timestamp is set to 0, but c037471 missed that, leading to a confusing timestamp value after for example a DML on a freshly-created relation with no scans done on it yet. This impacted the following attributes for two system views: - pg_stat_all_tables.last_idx_scan - pg_stat_all_tables.last_seq_scan - pg_stat_all_indexes.last_idx_scan Reported-by: Robert Treat Analyzed-by: Peter Eisentraut Author: Dave Page Discussion: https://postgr.es/m/CABV9wwPzMfSaz3EfKXXDxKmMprbxwF5r6WPuxqA=5mzRUqfTGg@mail.gmail.com Branch ------ master Details ------- https://git.postgresql.org/pg/commitdiff/d7744d50a5394db8d973d1cfa034ed6640aec13c Modified Files -------------- src/backend/utils/adt/pgstatfuncs.c | 8 +++++++- src/test/regress/expected/stats.out | 6 ++++++ src/test/regress/sql/stats.sql | 1 + 3 files changed, 14 insertions(+), 1 deletion(-)
