Do the global/ directories for the 17 and 18 clusters contain a
pgactive.stat file?
Without knowing anything about pgactive in particular (it's a
third-party extension)... It sure looks like that extension, or else
something related to it, has put a random file into the DB internals
in a way that won't pass our checksum verification. It needs to go
somewhere else.
