Dunno if this is any help, but on a 7.2 system I saw a REINDEX which
was interrupted leave the index at least partially working.  We ended
up with an index which seemed fine, but which didn't contain certain
rows (so those rows were not visible when the SELECT criterion was
the indexed field).  This was extremely puzzling, but a DROP INDEX;
CREATE INDEX pair solved it.
