Is there any way to invoke Java API from PostgreSQL

Hi,
Is there any way to invoke Java API from PostgreSQL? We need to transfer data between PostgreSQL and Oracle and oracle_fdw is not allowed due to security concerns in the environment. Also one of PostgresQL in Azure PostgreSQL and others are open source on prem.


Regards,
Aditya.

Honestly, what you are saying is that you aren't allowed to use a firecracker due to fire concerns, but is there a way to use dynamite instead.  If fdw isn't allowed, then callouts to other language environments shouldn't be allowed either.

Hi Erik,
Sincere apologies. Maybe  I wasn't clear. We need to transfer data between Azure PostgreSQL to On Prem Open Source PostgreSQL and Azure PostgreSQL to on Prem Oracle. Azure PostgreSQL is not allowing outgoing traffic through DB Links outside the same region. That's where we are looking for API-like solutions.

Regards,
Aditya.

If the issue is about managed Azure PG replication and regions, you may want to setup a bastion PG host that you manage in the same region that is used to act as a coordination point.  Just an idea.  In general, I think this list is about PG specific issues, not about how to work around cloud specific implementations of security measures that may impact global implementations.  The same issues could apply for MySQL replication as well.  PG does have Java api integration, but cloud providers limit what can be done on their own implementations for security reasons.  These aren't PG issues, they are provider issues.

Why not use PG replicate to a server that you do control (that might be Erik's "bastion" suggestion), or pg_dump/restore to a similar server, and then execute the business logic and ETL over to Oracle from there?

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.

Aditya.
