You haven't really provided any information about what changed around the
time this started happening.  What I'd wonder about is concurrent DDL on
these tables --- perhaps you added some kind of background maintenance
task that wasn't there before?

You might try enabling query logging (log_statement = all) to see exactly
what's happening at the time you get one of these errors.
