Oracle and SQL Server Compatibility for Community PostgreSQL
One compatibility layer that lets Oracle and SQL Server applications run on Community PostgreSQL with their original functions, data types, and semantics intact. Pick your source database to explore the full coverage.
More Oracle and SQL Server compatibility than any other vendor, and it is not close.
Runs on Community PostgreSQL - no commercial fork neededThe deepest Oracle compatibility layer available
Oracle types, functions, and packages on Community PostgreSQL - from NVL, DECODE, and TO_CHAR to DBMS_SCHEDULER, DBMS_SQL, UTL_HTTP, and DBMS_CRYPTO.
100% SQL Server (T-SQL) routine compatibility
SQL Server (T-SQL) functions, data types, and operators on Community PostgreSQL - DATEADD, DATEDIFF, CHARINDEX, ISNULL, TRY_CONVERT, COMPRESS, OPENJSON, nvarchar, and hierarchyid - all at native speed.
AI and migration tools cannot recreate Oracle and SQL Server built-in routines on PostgreSQL.HexaBridge does - so HexaRocket can deliver 100% automatic schema conversion.
Move Oracle and SQL Server workloads onto Community PostgreSQL without rewriting every function, type, and built-in by hand.
HexaBridge installs on standard Community PostgreSQL with a simple CREATE EXTENSION. No commercial database fork, no lock-in.
Boundary-crossing date math, NULL handling, collation, and edge cases behave the way Oracle and SQL Server do - not just same-named placeholders.
Logic-heavy functions are written in C; direct maps are inlined by the planner, so compatibility does not cost you performance.
HexaBridge is available to customers who migrate their databases using HexaRocket, and to customers of HexaCluster-approved partners. Contact us to learn how it accelerates your Oracle or SQL Server to PostgreSQL migration.
