How to Fix: Solve Error without installing PostgreSQL on Mac? dyld: Library not loaded: libpq.5.dylib

                The primary reason for this error is that libpq.5.dylib is not being loaded by dyld due to a missing library. This could be caused by various reasons such as an outdated or corrupted system library cache, or a mismatch between the PostgreSQL version in the Docker container and the system's library versions.Another possible cause is that the PostgreSQL version in the Docker container is not compatible with the TablePlus software on Mac OS X.

            ✅ Best Solutions to Fix It

                Using Homebrew to install libpq.5.dylib without installing PostgreSQL

                    Step 1: Open a terminal and run the command 'brew link pq --force' to link the pq package to the system's library cache.Step 2: Then, run the command 'brew link pq --force' again to update the link.Step 3: This method will install libpq.5.dylib without installing the entire PostgreSQL server software.Step 4: After completing these steps, restart TablePlus and try performing the backup again.



                Using Docker's built-in library support

                    Step 1: Check if the Docker container has the necessary libraries installed by running the command 'docker inspect -f {{.Config.Labels}}' inside the container.Step 2: If libpq.5.dylib is not present, try adding the following line to the Dockerfile: `RUN apt-get update && apt-get install -y libpq-dev` before copying the PostgreSQL image.Step 3: This method will ensure that the necessary libraries are installed within the Docker container, eliminating the need for additional installation steps on the host system.


            💡 Conclusion
            By following one of these methods, you should be able to resolve the 'dyld: Library not loaded: libpq.5.dylib' error and complete your backup of the PostgreSQL 13 database running inside a Docker container using TablePlus on Mac OS X.
