ANALYZE: "Invalid UNICODE character sequence found (0xfb5c30)" - Mailing list pgsql-general

I'm getting

ERROR:  Invalid UNICODE character sequence found (0xfb5c30)

when I run ANALYZE on my database.  The database is 7.3.2, with
backend/parser/gram.y from REL7_3_STABLE tip (as of last week, to fix
a problem with restores).  I did 'initdb' with '-E UNICODE'.  The data
is coming from an Access frontend via ODBC so I don't have a lot of
control over it.

Does this mean my database can't be ANALYZEd?
