This must be coming from calculate_database_size(). Is
$PGDATA/pg_tblspc actually missing? If the guy has no custom
tablespaces, I can believe that nothing except pg_database_size()
or pg_tablespace_size() would try to touch that subdirectory, so
he might not otherwise notice that it'd gone missing.

That's kind of in the category of "I don't believe it". I suspect pilot
error, ie he was talking to a different postmaster.
