Missing PSC attachment output for read replicas in PostgreSQL module

[yasra002]

TL;DR

The PostgreSQL module outputs instance_psc_attachment for the master instance but lacks a corresponding output for read replica PSC attachments, creating an inconsistency in the module's API.

Current Behavior

The module provides:

• ✅ instance_psc_attachment - PSC attachment for master instance
• ❌ Missing PSC attachment output for read replicas

Workaround

While users can technically extract PSC attachments from the replicas output:

# Current workaround
locals {
  replica_psc_attachments = [for r in module.postgresql.replicas : r.psc_service_attachment_link]
}

This approach requires users to understand the internal structure of the replicas output
