improved exception handling, skip tables that are causing errors

Incorrectly configured tables have previously led to the termination of the procedure
Untested for id based partitioning!

So this was a noble attempt to try and catch exceptions and move on to other partition sets, but there's far too many places that are going to be needed to try and catch issues. Testing this myself I kept running into more and more places that would need to be caught, especially when calling other functions. Rather than have some of these caught and not others, I'd rather not have this being handled at all so there's not some expectation that all the other places need to be caught and handled as well.

Thank you for the attempt, but I'll be undoing this commit on my end.

If there is some issue with partition maintenance not working with a specific table, the automatic_maintenance column in part_config can be set to off and the calls to run_maintenance() with no argument will skip those partition sets.
