For example, this visualizes a PostgreSQL Execution Plan in a very easily understandable format. Also points the node in plan where the cost is high. Helps developers. https://explain.depesz.com/s/Wa1v
The only problem is - a developer cannot choose this when he is dealing with sensitive data as the plans prepared using this website are stored somewhere else. If its made available with PMM, it could be easy as it will be stored locally in PMM server and available in future as well

What about improving PMM's QAN for PostgreSQL to include EXPLAIN plans visualization?
We can find much of the required work already done and contributed by Alex Tatiyants in the PostgreSQL Explain Visualizer (PEV), which is illustrated in more details in his post PostgreSQL Query Plan Visualization. His work has been in turn inspired by the "classic" Despez's PostgreSQL's explain analyze made readable.
Recently, pganalyze also included a similar feature in their product, which relies on PostgreSQL's auto_explain module.
PS: there's PMM-45-28 as well.
