Re: BUG #17994: Invalidating relcache corrupts tupDesc inside ExecEvalFieldStoreDeForm()

Me either. I think this might call for too much invention so I'm going 
to revert to plan A. The invalidation code won't be very much, and it 
should be a fairly rare event, so it doesn't need to be very clever.

The problem with rarely-executed code is that it's also hard to test.
			

Your Plan B in the end proved less difficult than I thought, and certainly seems more robust than having to tangle with invalidations. I didn't try to do anything to wrap the values in a bytea, it didn't seem necessary. Here's a patch - it's not terribly long or invasive. I haven't tried backpatching it yet.

cheers
