Upgrade considerations v15

Consider the following when upgrading EDB Postgres Advanced Server:

  • The pg_upgrade utility can't upgrade a partitioned table if a foreign key refers to the partitioned table.
  • If you're upgrading from the version 9.4 server or a lower version of EDB Postgres 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 EDB Postgres Advanced Server installation to a later version of EDB Postgres Advanced Server. To upgrade, you must:
    1. Use pg_dump to preserve the content of the subpartitioned table.
    2. Drop the table from the EDB Postgres Advanced Server 9.4 database or a lower version of EDB Postgres Advanced Server database.
    3. Use pg_upgrade to upgrade the rest of the EDB Postgres Advanced Server database to a more recent version.
    4. Use pg_restore to restore the subpartitioned table to the latest upgraded EDB Postgres Advanced Server database.
  • If you perform an upgrade of the EDB Postgres Advanced Server installation, you must rebuild any hash-partitioned table on the upgraded server.
  • If you're using an ODBC, JDBC, OCI, or .NET driver to connect to your database applications and upgrading to a new major version of EDB Postgres Advanced Server, upgrade your driver to the latest version when upgrading EDB Postgres Advanced Server.
