IvorySQL is an open-source, Oracle-compatible fork of PostgreSQL that remains a 100% drop-in replacement for the latest PostgreSQL. It adds an Oracle compatibility mode, PL/iSQL procedural language supporting Oracle PL/SQL syntax and packages, and Oracle built-in functions via the ivorysql_ora extension.

Use cases

  • migrate an Oracle database to open source without rewriting PL/SQL
  • run Oracle-style packages and procedures on PostgreSQL
  • switch between Oracle and PostgreSQL compatibility modes
  • use NVL, DECODE, TO_DATE and other Oracle built-in functions
  • self-host an enterprise relational database with Apache 2.0 license
  • lift-and-shift Oracle workloads to containers or Kubernetes

When to choose

  • you are migrating from Oracle and want to keep PL/SQL code largely unchanged
  • you need PostgreSQL compatibility plus Oracle syntax in one database
  • you want an open-source, vendor-lock-in-free Oracle alternative

When to avoid

  • you need a pure vanilla PostgreSQL with no Oracle extensions
  • you require full Oracle feature parity such as RAC or advanced Oracle-specific tooling
  • you need a lightweight embedded database
