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

Hello hackers,

Please take a look at the November report on buildfarm failures:
# SELECT br, COUNT(*) FROM failures WHERE dt >= '2025-11-01' AND
  dt < '2025-12-01' GROUP BY br;
REL_13_STABLE: 8
REL_14_STABLE: 10
REL_15_STABLE: 4
REL_16_STABLE: 11
REL_17_STABLE: 14
REL_18_STABLE: 22
master: 104
-- Total: 173
(Counting test failures only, excluding indent-check, Configure, Build
errors.)

# SELECT COUNT(*) FROM (SELECT DISTINCT issue_link FROM failures WHERE
  dt >= '2025-11-01' AND dt < '2025-12-01');
21

# SELECT issue_link, COUNT(*) FROM failures WHERE dt >= '2025-11-01' AND
  dt < '2025-12-01' GROUP BY issue_link ORDER BY 2 DESC LIMIT 6;
