Re: Improving tracking/processing of buildfarm test failures - Mailing list pgsql-hackers

Hello hackers,

Please take a look at the September report on buildfarm failures:
# SELECT br, COUNT(*) FROM failures WHERE dt >= '2025-09-01' AND
  dt < '2025-10-01' GROUP BY br;
REL_13_STABLE: 7
REL_14_STABLE: 3
REL_15_STABLE: 5
REL_16_STABLE: 7
REL_17_STABLE: 15
REL_18_STABLE: 27
master: 83
-- Total: 147
(Counting test failures only, excluding indent-check, Configure, Build
errors.)

# SELECT COUNT(*) FROM (SELECT DISTINCT issue_link FROM failures WHERE
  dt >= '2025-09-01' AND dt < '2025-10-01');
15

# SELECT issue_link, COUNT(*) FROM failures WHERE dt >= '2025-09-01' AND
  dt < '2025-10-01' GROUP BY issue_link ORDER BY 2 DESC LIMIT 6;
