Version 5.4.5¶

Released on 2023-10-26.

Note

If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.4.5.

We recommend that you upgrade to the latest 5.3 release before moving to 5.4.5.

A rolling upgrade from 5.3.x to 5.4.5 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 an issue that led to Received resultset tuples, but no field structure for them errors in clients using the PostgreSQL wire protocol, if a query was triggered after another query was suspended and left unconsumed.

Fixed an issue that led to Couldn't create execution plan from logical plan .. errors when trying to use a correlated join in the WHERE clause of a query with a join. For example:

SELECT
    n.nspname AS schema,
    t.typname AS typename,
    t.oid::int4 AS typeid
FROM
    pg_type t
    LEFT JOIN pg_catalog.pg_namespace n ON n.oid = t.typnamespace
WHERE
    EXISTS (
        SELECT 1 FROM pg_catalog.pg_type el WHERE el.oid = t.typelem);

Fixed an issue that prevented namespaces from showing up in pg_catalog.pg_namespace if a user had privileges on a table within a schema, but no privileges on the schema itself.

Fixed an issue that caused UNION to throw SQLParseExceptions instead of AmbiguousColumnExceptions, when 2 or more columns are assigned the same name. e.g.:

SELECT a FROM (SELECT a, b AS a FROM t UNION SELECT 1, 1) t2;
-- selecting 'a' from 't2' is ambiguous since there are 'a' and 'b AS a'

Fixed a regression introduced with CrateDB Version 5.3.0 that may cause INSERT INTO ... ON CONFLICT .. queries to fail with unexpected errors or even updating wrong sub-columns when using a sub-column expression in the ON CONFLICT clause.
Fixed an issue that caused UNION to return wrong results or throw SQLParseException when the output columns had identical names which were from tables that were aliased. e.g.:
```
SELECT * FROM (SELECT t1.a, t2.a FROM t AS t1, t AS t2) t3 UNION SELECT 1, 1;
```
where t1.a and t2.a are from aliased tables that also have identical names, a.
Fixed a regression, introduced in Version 4.2.0 which caused wrong HTTP error code to be returned, when some internal issue occurred during the creation of execution plan for a query, e.g.: shards of a table involved in the query become unavailable.
Fixed an issue that caused the properties of a INDEX using clause within a type definition for ARRAY(GEO_SHAPE) in a CREATE TABLE statement to be ignored.
