Key Improvements

Parallel Sequential Scan

Leverage PostgreSQL 16's new parallel sequential scan capability to access large table data faster through multiple processes.


-- Example query benefiting from parallel scanning:
SELECT * FROM (SELECT generate_series(1,10000000) as id) s
WHERE id % 7 = 0
ORDER BY id;

            

Improved JSON Support

Adminer now fully supports PostgreSQL 16's advanced JSON operations including:

  • JSON/JSONB path queries
  • Enhanced JSON functions and operators
  • Improved performance for large JSON datasets

Tip: Use the new to_jsonpath() function to construct JSON path expressions in Adminer's SQL editor.

Connection Pooling Enhancements

Adminer v4.9 integrates with PostgreSQL 16's connection pooling improvements for:

  • Smarter session management
  • Improved scalability for web applications
  • Reduced connection overhead

Requires PostgreSQL 16+ and appropriate pooling configuration.
