Re: Duplicate key ( reindex and vacuum full logs )

just for add informations on the problem:
these are the logs received by the reindex and by
vacuum full on that table ( before to delete the
duplicated rows):

===== REINDEX =======

Start Reindex table ua_user_data_exp at Fri Sep 5 07:12:26 CEST 2003
ERROR: Cannot create unique index. Table contains non-unique values

===== VACUUM FULL ======

Start Vacuum table ua_user_data_exp at Fri Sep 5 07:13:11 CEST 2003
