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

Hello hackers,

Please take a look at the May report on buildfarm failures:
# SELECT br, COUNT(*) FROM failures WHERE dt >= '2026-05-01' AND
  dt < '2026-06-01' GROUP BY br;
REL_14_STABLE: 9
REL_15_STABLE: 6
REL_16_STABLE: 26
REL_17_STABLE: 26
REL_18_STABLE: 22
master: 164
-- Total: 253
(Counting test failures only, excluding indent-check, Configure, Build
errors, also excluding failures from fruitcrow..)

# SELECT COUNT(*) FROM (SELECT DISTINCT issue_link FROM failures WHERE
  dt >= '2026-05-01' AND dt < '2026-06-01');
25

# SELECT issue_link, COUNT(*) FROM failures WHERE dt >= '2026-06-01' AND
  dt < '2026-06-01' GROUP BY issue_link ORDER BY 2 DESC LIMIT 6;
