Duplicate Index Creation

Howdy,

Environment:

Postgres 8.4.7 64-bit
Solaris 10

I create an index as:

CREATE INDEX i1
ON input_transaction_snbs
USING btree
(trans_client);

which is creating a 2nd duplicate index in error as this query shows:

SELECT idstat.relname AS table_name,
idstat.indexrelname AS index_name,
idstat.idx_scan AS times_used,
pg_size_pretty(pg_relation_size(idstat.relid)) AS table_size,
pg_relation_size(indexrelid) AS index_size,
n_tup_upd + n_tup_ins + n_tup_del as num_writes
FROM pg_stat_user_indexes AS idstat
JOIN pg_indexes ON indexrelname = indexname
JOIN pg_stat_user_tables AS tabstat ON idstat.relname = tabstat.relname
WHERE indexdef !~* 'unique'
AND idstat.relname = 'input_transaction_snbs'
ORDER BY index_size desc;

Results of the above SELECT:

table_name | index_name | times_used | table_size | index_size | num_writes
------------------------+------------+------------+------------+------------+------------
input_transaction_snbs | i1 | 0 | 2932 MB | 304242688 | 10350357
input_transaction_snbs | i1 | 0 | 2932 MB | 304242688 | 10350357
(2 rows)

This is causing poor query performance. Any ideas?

Thank you,
