That's the wrong query. The files on disk are relefilenodes not
oids. Try WHERE pg_relation_filenode(oid) IN ...
Oh, okay, but still:
% sudo -H -u postgres psql mydb -c "SELECT pg_relation_filenode(7877054);"
pg_relation_filenode

% sudo -H -u postgres psql mydb -c "SELECT pg_relation_filenode(7877056);"

pg_relation_filenode accepts the OID of a table. For what you're trying
to do you'd need pg_relation_filenode(tablespace oid, relfilenode).
