Added support for Hive partitioning when creating analytical tables using the metastore.add_table stored procedure. You can now specify the optional fourth parameter to partition an analytical table.

For more information, refer to Chapter 30 and Section 25.1.1.

Added the axe.use_postgres_snapshot configuration parameter to avoid holding the transaction horizon. When set to false, Postgres Pro snapshots are not used for queries that do not work with heap tables, which allows VACUUM to delete dead tuples, preventing table bloat.

For more information, refer to Chapter 31.

Added support for UNION operations between Postgres Pro heap tables and views created for Parquet files in regular SELECT commands, as well as between two heap tables in the metastore.copy_table stored procedure.

Added the ability to retrieve statistics for analytical tables, including overall table statistics and column-level statistics, from the metadata catalog.

For more information, refer to Chapter 39.

Split the expire_snapshot stored procedure into two separate procedures: metastore.expire_snapshot_on_time, for marking snapshots as expired based on their creation date and time, and metastore.expire_snapshot_on_ids, for marking snapshots as expired based on their IDs.

For more information, refer to Section 29.4.

Added the ability to configure Parquet file storage parameters, such as the compression algorithm, compression level, and the number of rows in a row group, when creating Parquet files.

For more information, refer to Section 29.3.

Added force and cascade parameters to the metastore.remove_table stored procedure. The force parameter specifies whether to drop the Postgres Pro view created for the analytical table. The cascade parameter specifies whether to drop all views based on this view.

For more information, refer to Section 25.4.

Added the optional third parameter to the metastore.create_view stored procedure that specifies whether to drop an existing Postgres Pro view with the same name before creating a new view.

For more information, refer to Section 25.3.

Added the metastore.pgpro_build() stored procedure for retrieving the pgpro_metastore build number.

For more information, refer to Chapter 20.

Added functions for working with simple secrets and improved compatibility with S3 storages.

For more information, refer to Chapter 23 and Chapter 24.

Added the metastore.mgrant and metastore.mrevoke stored procedures for granting and revoking privileges on pgpro_metastore objects.

For more information, refer to Section 22.4.

Optimized the pgpro_axe columnar-vectorized analytics engine to provide high performance on virtual machines with SSE4.2 and later vector CPU instructions. SSE2 is the minimum requirement.

For more information, refer to Chapter 13.

Added support for Red Hat Enterprise Linux (RHEL) 10.

For more information, refer to Chapter 13.

Fixed the following errors that occurred when working with S3 storages:

Fixed errors that occurred when using the COPY command with pgpro_scheduler.
