OCI Database with PostgreSQL Versions and Upgrades
Details about supported OCI Database with PostgreSQL system versions and version upgrade schedule.
The supported major versions of PostgreSQL are 14, 15, and 16.
Upgrades
When a new minor version of a major version is released, existing database systems are automatically upgraded to the new minor version during their maintenance windows. You can't change the minor version manually.
You need to create a new database system to upgrade major versions. You can use native PostgreSQL utilities such as pg_dump and pg_restore for major version upgrades. For an example, see Importing, Exporting, and Migrating Databases in OCI Database with PostgreSQL.
