## Summary
PostGIS is once again available for Amazon Linux 2023 via the PostgreSQL RPM repository. The update includes the SFCGAL library and supports PostgreSQL versions 14 through 18 on both x86_64 and aarch64 architectures. While some GDAL drivers are missing due to distribution limitations, core functionality remains intact.

## Technical details of the PostGIS restoration
- Supports **PostgreSQL 14 to 18** on **x86_64** and **aarch64**.
- Includes **SFCGAL 2.3.0**, which requires new build-time packages **CGAL 6.1.2** and **nlohmann_json 3.12.0** for Amazon Linux 2023.
- Uses **rpath** to link against specific versions (e.g., **GDAL 3.13.3**, **GEOS 3.15.0**, **PROJ 9.8.1**) without replacing the OS-provided libraries.
- **GDAL** is built without certain drivers not provided by the distribution, such as **netCDF**, **HDF5**, **xerces-c**, and **Arrow/Parquet**.
- Core drivers like **GeoTIFF**, **GeoPackage**, and **SpatiaLite** are fully supported.

## Why it matters
This restores critical geospatial capabilities to users running PostgreSQL on Amazon Linux 2023, specifically adding advanced computational geometry support via SFCGAL.
