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
