Version 5.2.2

Released on 2023-02-09.

Note

If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.2.2.

We recommend that you upgrade to the latest 5.1 release before moving to 5.2.2.

A rolling upgrade from 5.1.x to 5.2.2 is supported. Before upgrading, you should back up your data.

Warning

Tables that were created before CrateDB 4.x will not function with 5.x and must be recreated before moving to 5.x.x.

You can recreate tables using COPY TO and COPY FROM or by inserting the data into a new table.

Fixes

  • Fixed crate-node cli tool to work without asking for path.home and/or path.conf parameters when run from inside the CrateDB distribution directory, for Linux, MacOSX and Windows environments.

  • Removed the automatic fix mechanism, introduced in 5.2.1, for corrupted metadata due to table swap statements like:

    ALTER CLUSTER SWAP TABLE "myschema"."mytable" TO "myschema.mytable";

    and provide a manual way to fix such issues by running:

    bin/crate-node fix-metadata

  • Changed the typsend and typreceive values in the pg_catalog.pg_type table to match PostgreSQL for improved compatibility. Clients like Postgrex depend on this.

  • Fixed a race condition that could lead to an error reporting that a partition was not found when running DELETE FROM <table> WHERE partition_column = ? statements.

  • Fixed runtime ClassCastException when attempting to ORDER BY an INTERVAL type, or when attempting to use MIN or MAX aggregations on an INTERVAL type, and return an error message about unsupported type during analysis of a query.

  • Disallowed comparison operators between INTERVAL types, except for = and <>, Previously, null was returned in any of the >, >=, <, <=, comparisons.
