Introduction

PostGIS is a spatial database extender for PostgreSQL that allows users to store and query geospatial data. However, installing PostGIS 3.5.2 for PostgreSQL 17 using the Stack Builder can be a challenging task. In this article, we will discuss the common issues that may arise during the installation process and provide a step-by-step guide to troubleshoot and resolve the problems.

Common Issues with PostGIS 3.5.2 Installation

When attempting to install PostGIS 3.5.2 for PostgreSQL 17 using the Stack Builder, users may encounter the following errors:

Invalid h3.dll file: The installation process may fail with an error message indicating that the h3.dll file in the library is invalid. The file version is 15, but the server requires a higher version.
Missing dependencies: The installation may fail due to missing dependencies, such as the PostgreSQL 17 server not being installed or configured correctly.
Incompatible versions: The installation may fail due to incompatible versions of PostGIS and PostgreSQL.

Troubleshooting the Invalid h3.dll File Error

To troubleshoot the invalid h3.dll file error, follow these steps:

Step 1: Check the PostgreSQL 17 Server Version

Ensure that the PostgreSQL 17 server is installed and configured correctly. You can check the server version by running the following command in the PostgreSQL command-line interface:

SELECT version();

This command will display the version of the PostgreSQL server.

Step 2: Update the PostgreSQL 17 Server

If the PostgreSQL 17 server is not up-to-date, update it to the latest version. You can update the server by running the following command:

sudo apt-get update
sudo apt-get upgrade postgresql-17

Step 3: Reinstall the PostGIS 3.5.2 Package

After updating the PostgreSQL 17 server, reinstall the PostGIS 3.5.2 package using the Stack Builder. Ensure that you select the correct version of PostGIS and PostgreSQL during the installation process.

Step 4: Verify the h3.dll File Version

After reinstalling the PostGIS 3.5.2 package, verify that the h3.dll file version is updated to the latest version. You can check the file version by running the following command:

ldd /usr/lib/postgresql/17/lib/postgis-3.5.so

This command will display the version of the h3.dll file.

Resolving Missing Dependencies

To resolve missing dependencies, follow these steps:

Step 1: Install the Required Dependencies

Ensure that all required dependencies are installed. You can install the dependencies by running the following command:

sudo apt-get install postgresql-17-postgis-3-5

Step 2: Reinstall the PostGIS 3.5.2 Package

After installing the required dependencies, reinstall the PostGIS 3.5.2 package using the Stack Builder. Ensure that you select the correct version of PostGIS and PostgreSQL during the installation process.

Resolving Incompatible Versions

To resolve incompatible versions, follow these steps:

Step 1: Check the PostGIS and PostgreSQL Versions

Ensure that the versions of PostGIS and PostgreSQL are compatible. You can check the versions by running the following commands:

SELECT postgis_full_version();
SELECT version();

These commands will display the versions of PostGIS and PostgreSQL.

Step 2: Update the PostGIS Version

If the versions of PostGIS and PostgreSQL are incompatible, update the PostGIS version to the latest version that is compatible with the PostgreSQL version. You can update the PostGIS version by running the following command:

sudo apt-get install postgresql-17-postgis-3-5

Step 3: Reinstall the PostGIS 3.5.2 Package

After updating the PostGIS version, reinstall the PostGIS 3.5.2 package using the Stack Builder. Ensure that you select the correct version of PostGIS and PostgreSQL during the installation process.
