Explanation
NDB supports patching for PostgreSQL database instances. Patching for PostgreSQL is validated on VMs provisioned by NDB (greenfield deployments). To patch PostgreSQL database server VMs, you must create a software profile version by uploading the PostgreSQL update file in NDB. You can then use the PostgreSQL update to patch other database server VMs or provision a new database server VM with the updated software profile. The first step in the NDB patching workflow is to create a software profile version with the desired PostgreSQL version.
