PostgreSQL Migration Pathways on Azure

   • Lacks support for many Oracle-compatible features, e.g., Pro*C, Bulk Data Loader, PL/SQL Debugger etc.
   • Difficult for Oracle Developers/DBAs to adopt.
   • Limited Security features.
   • Self-supported database. No vendor technical support available.
2. EDB Postgres Advanced Server on Azure Cloud (Self-managed or Fully Managed)
   • Built on open-source PostgreSQL, but enhanced with addition of many enterprise-class features and tools.
   • All these and most other Oracle compatible features are supported.
   • Easy for Oracle Developers/DBAs to adopt since it understands and executes Oracle’s PL/SQL commands natively without performance issues and without difficult-to-debug emulation.
