You must install at least one postgresql-client- package

In order to fix the error “you must install at least one postgresql-client- package”, you need to install a PostgreSQL client package with a specific version. This message typically occurs when you try to run a command or program that requires the PostgreSQL client, but it is not installed on your system or the version installed does not match the required version.

To resolve this issue, follow the steps below:

1. Identify the required version of the PostgreSQL client package. This information is usually mentioned in the error message or in the documentation of the command or program you are trying to use.
2. Install the appropriate version of the PostgreSQL client package using the package manager of your operating system. Below are some examples for different package managers:
   • Ubuntu/Debian: Use the apt package manager to install the specific version. For example, if the required version is 9.6, you can run sudo apt install postgresql-client-9.6.
   • CentOS/RHEL: Use the yum package manager to install the specific version. For example, if the required version is 10, you can run sudo yum install postgresql10.
   • Mac OS X: Use the Homebrew package manager to install the specific version. For example, if the required version is 11, you can run brew install postgresql@11.
   • Windows: Download the specific version of the PostgreSQL client package installer from the official PostgreSQL website and run the installer.
3. After installing the required PostgreSQL client package, try running the command or program again. It should now be able to find and use the installed client.

Keep in mind that the package names and installation commands may vary depending on your operating system and the specific version of the PostgreSQL client you need. Make sure to replace the <version> placeholder in the error message with the appropriate version number.
