The following bug has been logged online:

Bug reference:      3707

Description:        failure cases in reindex don't always report enough
information to diagnose the issue
Details:

If you issue a REINDEX DATABASE, which then fails due to db corruption (i.e.
could not create index due to duplicate values), the resulting error message
only specifies:
ERROR:  could not create unique index
DETAIL:  Table contains duplicated values.


without telling you what table actually triggered the error. It *can* be
tracked down by manually looking up the oid of the last table that was
successfully indexed and manually iterating from there, but it'd be nice to
know directly.

Hmm.  It would be fairly easy to mention the index name here (less so to
mention the table name, but I think you'd really need to know which
index is the problem, anyway).  ISTR that when this error message was
written the index *wasn't* known at the place where the message was
being emitted, but we do have it now ...
