oid file, but no pg_class row for it

[Ed L.]

While dealing with filesystem bloat issues, I found a large file
named 43710738, recently updated and sitting in one of my
database directories,

$ ls -lh ../../../data/base/11259315/43710738
-rw------- 1 dba dba 1016M Nov 3 17:05 ../../../data/base/11259315/43710738

.... with no corresponding entry that I can find in pg_class with
that oid (I thought they were all in there). I tried dumping the
database, knowing the oids are in the comments, but found
nothing there. pg_filedump'ing the file doesn't seem to be
helpful, either.

Anyone have any tips on how to figure out what this oid maps to?

TIA.

Look at relfilenode, not OID.
