duplicate key value violates unique constraint "pg_statistic_relid_att_inh_index" while performing full vacuum on the database

[Raghavendra Rao J S V]

Hi,


While performing vacuum full, I have  received the below highlighted error.
Please guide me how to resolve this issue.


​/opt/postgres/9.2/bin/psql -p 5433 --username=cmuser  cpcm -c "*VACUUM
FULL ANALYZE*;"


ERROR:  *duplicate key value violates unique constraint
"pg_statistic_relid_att_inh_index"*
DETAIL:  Key (starelid, staattnum, stainherit)=(18915, 6, f) already exists.

' pg_statistic ' is a meta data table. Is it ok if I remove one duplicated
record from ' pg_statistic' table?.
