General changes

SQL language changes

Bug fixes

  • The Cluster Node Map and the Debug Page that lists cluster localities are now available again to non-admin users. This fixes a bug introduced in v19.2.3. #53332
  • Fixed a bug that could cause backfills to fail with a vague TransactionStatus error as they are completing. #53765
  • Fixed a bug that could cause CockroachDB to crash when evaluating queries with window functions with the GROUPS mode of framing when OFFSET FOLLOWING boundary was used and when the offset was a very large value such that it could result in an integer overflow. #53758
  • Fixed a bug that could cause CockroachDB to crash when using a RANGE-mode window function with an offset in some cases (e.g, OVER (PARTITION BY b ORDER BY a RANGE 1 PRECEDING). #54074
  • Adding a NOT NULL constraint no longer fails with the error check ... does not exist. #54290
  • A NOT VALID foreign key constraint no longer fails with the internal error table descriptor is not valid: duplicate constraint name. #54290
  • Fixed a bug that could cause columns used in an index containing foreign key columns as a prefix to lead to all of the index columns being set to NULL or the default value on CASCADE. #54592
  • Fixed a rare bug that could lead to index backfills failing on transaction restarts. #54860
