Upgrade considerations v13

The following limitations apply to upgrading EDB Postgres Advanced Server:

• The pg_upgrade utility cannot upgrade a partitioned table if a foreign key refers to the partitioned table.
• If you are upgrading from the version 9.4 server or a lower version of Advanced Server, and you use partitioned tables that include a SUBPARTITION BY clause, you must use pg_dump and pg_restore to upgrade an existing Advanced Server installation to a later version of Advanced Server. To upgrade, you must:
  1. Use pg_dump to preserve the content of the subpartitioned table.
  2. Drop the table from the Advanced Server 9.4 database or a lower version of Advanced Server database.
  3. Use pg_upgrade to upgrade the rest of the Advanced Server database to a more recent version.
  4. Use pg_restore to restore the subpartitioned table to the latest upgraded Advanced Server database.
• If you perform an upgrade of the Advanced Server installation, you must rebuild any hash-partitioned table on the upgraded server.
