Is there any approach to achieve the same result in Postgresql?
Anyone sharing the need of this functionality?
Tnx!
Can you elaborate what exact problem are you trying to solve here?
looking at the article you sent:
"Some DBA tasks, like creating private database links or setting up jobs using the DBMS_JOB package, require the administrator to log in as a specific user. This can present a problem if the administrator doesn't know the password."
"You have multiple developers working in a shared schema. Letting multiple people share the same credentials represents a security risk. Instead you create a separate proxy user for each individual, allowing them to connect to the schema owner with their own credentials. If a user leaves a project, you simply lock or drop their user, and they no longer have access to the shared schema."
It's totally not needed in Postgres as the architecture and the concept of schema and users is different and you don't have any credentials to the schema, which is just a namespace in postgres
