Re: Is there any way to invoke Java API from PostgreSQL

Thanks Steve!! All of the below are supported for DB Links.
Postgres VM - Oracle 12 c
Postgres VM - Azure Postgres
Azure Postgres - Azure Postgres
Oracle - Postgres VM
Oracle - Azure Postgres

Stuck with anything that is outgoing from Azure Postgres. Will check
Bastion Host or try pg_dump/restore.

Regards,
Aditya.
