Some cursory trawling in the REL7_3 sources says that this means that
"SELECT DISTINCT loid FROM pg_largeobject" found a large object OID
that then could not be found by an indexscan of pg_largeobject. So
I'd try a REINDEX of pg_largeobject to see if that fixes it. See the
REINDEX man page concerning hoops you have to jump through to reindex
a system catalog --- IIRC, the hoops are much higher and narrower back
in 7.3.

Of course, I'm reading 7.3.15 sources ...
