It's a memory usage map. Your problem is evidently here:

As far as I recall at the moment, MessageContext is used to parse,
analyze, and possibly to plan an incoming query. So the short answer is
that you're trying to run a query that's too long and/or too complicated.
We'd need a lot more details before suggesting how you might work around
that.
