I think this is another one that falls under the general fix all:
run the "vacuum" command.

Re: [GENERAL] what on earth does this mean?!?
Thanks KT

Vacuum sadly does not help.

Is there anyone out there who actually knows what this message *means*? Not
necessarily specifically for 21400 of course, but in general?

  ERROR:  RelationCatalogInformation: Relation 21400 not found

Regards, K.
