Installing PostGIS SFCGAL 1.4 Extension in the Latest Official PostGIS Docker Image (Debian Bullseye Based)

In this article, we will explore the process of installing the PostGIS SFCGAL 1.4 extension in the latest official PostGIS Docker image, which is based on Debian bullseye. The PostGIS SFCGAL extension is a powerful tool for working with 3D geometry and topology in PostGIS, and its latest version (1.4.1 at the time of writing) is a significant improvement over its predecessors.

The PostGIS SFCGAL 1.4 extension is a crucial component of any PostGIS-based spatial database, as it provides a wide range of features and functions for working with 3D geometry and topology. Some of the key benefits of using PostGIS SFCGAL 1.4 include:

Improved performance: PostGIS SFCGAL 1.4 is optimized for performance, making it ideal for large-scale spatial databases and applications.
Enhanced functionality: The extension provides a wide range of functions and features for working with 3D geometry and topology, including support for 3D spatial relationships and topology.
Better support for 3D spatial data: PostGIS SFCGAL 1.4 provides better support for 3D spatial data, including support for 3D points, lines, and polygons.

Before installing the PostGIS SFCGAL 1.4 extension, you will need to have the following prerequisites in place:

PostGIS Docker image: You will need to have the latest official PostGIS Docker image installed on your system.
Debian bullseye: The PostGIS Docker image is based on Debian bullseye, so you will need to have this version of Debian installed on your system.
Libsfcgal system library: The PostGIS SFCGAL extension requires the libsfcgal system library, which you will need to install separately.

To install the PostGIS SFCGAL 1.4 extension, you will need to follow these steps:

Step 1: Pull the Latest PostGIS Docker Image

First, you will need to pull the latest PostGIS Docker image from the Docker Hub. You can do this by running the following command:

docker pull postgis/postgis:14-3.3

This will download the latest PostGIS Docker image and make it available on your system.

Step 2: Run the PostGIS Docker Container

Once you have pulled the latest PostGIS Docker image, you can run the PostGIS Docker container by running the following command:

docker run -d --name postgis -p 5432:5432 postgis/postgis:14-3.3

This will start a new PostGIS Docker container and make it available on your system.

Step 3: Install the Libsfcgal System Library

Next, you will need to install the libsfcgal system library, which is required by the PostGIS SFCGAL extension. You can do this by running the following command:

docker exec -it postgis apt-get update
docker exec -it postgis apt-get install -y libsfcgal-dev

This will install the libsfcgal system library and its development headers on the PostGIS Docker container.

Step 4: Install the PostGIS SFCGAL Extension

Once you have installed the libsfcgal system library, you can install the PostGIS SFCGAL extension by running the following command:

docker exec -it postgis psql -U postgres -d postgres -c "CREATE EXTENSION IF NOT EXISTS sfcgal;"

This will install the PostGIS SFCGAL extension on the PostGIS Docker container.

Step 5: Verify the PostGIS SFCGAL Extension

Finally, you can verify that the PostGIS SFCGAL extension has been installed correctly by running the following command:

docker exec -it postgis psql -U postgres -d postgres -c "SELECT postgis_full_version();"

This will display the version of PostGIS that is installed on the Docker container, including the version of the PostGIS SFCGAL extension.

In this article, we have explored the process of installing the PostGIS SFCGAL 1.4 extension in the latest official PostGIS Docker image, which is based on Debian bullseye. The PostGIS SFCGAL extension is a powerful tool for working with 3D geometry and topology in PostGIS, and its latest version (1.4.1 at the time of writing) is a significant improvement over its predecessors. By following the steps outlined in this article, you can install the PostGIS SFCGAL extension and start working with 3D spatial data in PostGIS.

If you encounter any issues while installing the PostGIS SFCGAL extension, you can try the following troubleshooting steps:

Check the Docker logs: You can check the Docker logs to see if there are any errors or warnings that may be related to the installation of the PostGIS SFCGAL extension.
Verify the libsfcgal system library: You can verify that the libsfcgal system library has been installed correctly by running the following command:
