Fixes

  • Fixed an issue in the error handling of CREATE REPOSITORY statements which could lead to a NullPointerException instead of a more meaningful error message.
  • Fixed an issue that could lead to a Can't handle Symbol error when using views which are defined with column aliases.
  • Fixed a regression that led to max aggregations on columns of type double precision or real to return null instead of 0.0 if all aggregated values are 0.0.
  • Fixed an issue that could lead to an OutOfMemoryError when retrieving large result sets with large individual records.
  • Fixed an issue that could lead to a NullPointerException when using a SELECT statement containing an INNER JOIN.
  • Fixed an issue in the PostgreSQL wire protocol that would cause de-serialization of arrays to fail if they contained unquoted strings starting with digits.
  • Fixed an issue that could lead to a serialization error when streaming values of the TIMESTAMP WITHOUT TIME ZONE type in text format using the PostgreSQL wire protocol.
