Fixes

  • Fixed an issue that caused queries on more than one relation and a literal FALSE in the WHERE clause to match all rows instead of no rows.
  • Fixed the following issues in the Admin UI:
    • Fixed an issue that prevents the value for nested partitioned columns showing up in the table partitions overview.
    • Fixed capitalization of Shards tab label.
    • Updated keywords list so that they are recognised and painted in red.
  • Fixed a bug which could lead to stuck queries when an error happens inside distributed execution plans, e.g., a CircuitBreakingException due to exceeded memory usage.
  • Fixed an issue that resulted in the values for nested partitioned columns to be missing from the result.
  • Fixed an issue that caused SELECT * to include nested columns of type geo_shape instead of only selecting top-level columns.
  • Fixed a bug that would lead to insertion of records via INSERT INTO ... (SELECT ... FROM ..) and INSERT INTO ... VALUES (...) into different partitions while using the same partition by value. This occurs only when the partition key is an object field of the timestamp data type.
  • Fixed an issue that caused subscript expressions on top of child relations in which an object column is selected to fail.
  • Fixed an issue in VALUES that would not allow combining expressions that can be explicitly casted or NULL literals in the same column.
  • Fixed a ClassCastException that occurred when querying certain columns from information_schema.tables, sys.jobs_log, or sys.jobs_metrics with a client connected via the PostgreSQL wire protocol.
  • Fixed a regression introduced in 4.0.11 which caused a ClassCastException when querying sys.allocations.
