Explanation

The ivory template uses Highgo’s open-source IvorySQL kernel, providing Oracle database compatibility.

Key Features:

  • Supports Oracle PL/SQL syntax
  • Compatible with Oracle data types (NUMBER, VARCHAR2, etc.)
  • Supports Oracle-style packages
  • Retains all standard PostgreSQL functionality

Use Cases:

  • Migrating from Oracle to PostgreSQL
  • Applications needing both Oracle and PostgreSQL syntax support
  • Leveraging PostgreSQL ecosystem while maintaining PL/SQL compatibility
  • Test environments for evaluating IvorySQL features

Notes:

  • IvorySQL 5 is based on PostgreSQL 18
  • Using liboracle_parser requires loading into shared_preload_libraries
  • pgbackrest may have checksum issues in Oracle-compatible mode, PITR capability is limited
  • The current package matrix covers EL 8/9/10, Debian 12/13, Ubuntu 22/24/26, and both architectures
