A reasonable bet is that the pg_namespace row for "public" has gotten
duplicated (either in reality, or there's an extra index entry for it).
Which would cause the join in psql's \dp query to show tables in that
schema twice. So what I'd like to see is the output of
select ctid,xmin,xmax,nspname from pg_namespace;
Also the exact backend version, as you previously mentioned.
A quick look through the 8.0.x CVS history shows at least one
long-since-fixed bug that could have resulted in duplicate rows or
duplicate index entries.
