Well, this is a bit unusual:

It's not normal to have so much stuff in TopMemoryContext. That could
represent a leak, but it's also possible that that's just management
overhead for all of these contexts:

That's a *heck* of a lot of SPI plans. You haven't provided any
information that would let anybody diagnose why you have so many,
though. Tell us about your usage patterns, especially of PL-language
functions.
