    • Fixed handling of tables with multilevel partitioning. Previously, SELECT FOR SHARE and SELECT FOR UPDATE commands for such tables could return the following error: ERROR: variable not found in subplan target lists.

    • Enhanced pg_pathman stability.

E.22.2. Migration to Version 10.9.1

If you are upgrading from a Postgres Pro Enterprise release based on the same PostgreSQL major version, it is enough to install the new version into your current installation directory.

When upgrading from versions 10.6.2 or lower, you must run the REINDEX command to rebuild GIN, GiST, and SP-GiST indexes to fix replication issues that could be observed in these versions. You should also retake all backups for these versions if your database had such indexes.

When upgrading from versions 10.3.3 or lower, you have to rebuild GiST indexes built over columns of the intarray type, as well as indexes that use mchar or mvarchar types.

To migrate from PostgreSQL, as well as Postgres Pro Standard or Postgres Pro Enterprise based on a previous PostgreSQL major version, see the migration instructions for version 10. If you are opting for a dump/restore, make sure to use the --add-collprovider option to correctly choose the provider for the default collation of the migrated database.
