Feature request

Is your feature request related to a problem? Please describe.
Currently it's not trivial to figure out how well a query is supported by indices or sequences. This either requires using PMM, validating the query manually or extract it and running EXPLAIN on it manually.

Describe the solution you'd like
The profiler should allow doing this automatically and ideally also parse the results so queries without indices or sequences can be shown as problematic without any manual work.

Research direction

No files, tests, or entry points are identified in the issue. Start by locating how the profiler collects queries, then determine where EXPLAIN results could be gathered and parsed; done means queries lacking index or sequence support are automatically identified as problematic.
