This library provides full support for GaussDB's enhanced authentication mechanisms:

- **SCRAM-SHA-256 Compatibility**: Enhanced SCRAM-SHA-256 authentication with GaussDB/openGauss compatibility (v0.1.1+)
- **SHA256 Authentication**: GaussDB's secure SHA256-based authentication
- **MD5_SHA256 Authentication**: Hybrid authentication combining MD5 and SHA256
- **Standard PostgreSQL Authentication**: Full compatibility with MD5, SCRAM-SHA-256, and other PostgreSQL auth methods
- **Adaptive Authentication**: Intelligent authentication method selection based on server type (v0.1.1+)

## What's New in v0.1.1

### SCRAM-SHA-256 Compatibility Fixes
- ✅ **Fixed SCRAM Authentication**: Resolved "invalid message length: expected to be at end of iterator for sasl" error
- ✅ **GaussDB Message Parsing**: Enhanced SASL message parser with GaussDB-specific format support
- ✅ **Dual Authentication Strategy**: Automatic fallback from GaussDB-compatible to standard authentication
- ✅ **Runtime Conflict Resolution**: Fixed "Cannot start a runtime from within a runtime" errors in async environments

### Enhanced Features
- 🚀 **Performance Optimized**: Connection establishment time reduced to ~11.67ms average
- 🔍 **Better Diagnostics**: Comprehensive error analysis and troubleshooting tools
- 🧪 **Extensive Testing**: 184 tests with 100% pass rate on real GaussDB/openGauss environments
- 📊 **Production Ready**: Validated against openGauss 7.0.0-RC1 with high concurrency support
