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

Hello hackers,

Please take a look at the January report on buildfarm failures:

# SELECT br, count(*) FROM failures WHERE dt >= '2025-01-01' AND
  dt < '2025-02-01' GROUP BY br;
REL_13_STABLE: 1
REL_14_STABLE: 1
REL_15_STABLE: 4
REL_16_STABLE: 12
REL_17_STABLE: 10
master: 64
-- Total: 92
(Counting test failures only, excluding indent-check, Configure, Build
errors.)

# SELECT COUNT(*) FROM (SELECT DISTINCT issue_link FROM failures WHERE
  dt >= '2025-01-01' AND dt < '2025-02-01');
19

# SELECT issue_link, count(*) FROM failures WHERE dt >= '2025-01-01' AND
  dt < '2025-02-01' GROUP BY issue_link ORDER BY 2 DESC LIMIT 4;
