We have been using 40 characters in some columns, in some others 60 for plugin_name.

We should adjust isValidPluginName method to check the length in the regex and if not valid, throw an exception? It may be painful for some people to rename the plugin but at least on Marketplace the length has been already enforced.

The Marketplace itself enforces a length of 40 characters. Happy to increase this to 60 characters if better.

We want to make sure that

• Marketplace and Matomo itself validate plugin name
• All DB columns use same length
