I started using CLUSTER a few weeks ago and it worked (no errors) and the performance of the database improved. However, When I ran CLUSTER again, I got the following error: ERROR: cannot create pg_temp_2558977013: File exists Here is more information that may or may not be relevant: 1. I am running PostgreSQL 7.3.1. 2. The table has a little more than 16 million records 3. I am pretty sure I am not running out of disk space: The size of the partition is 126 gigabytes and only 28 gigabytes are used. 4. The table has 5 columns: (int, date, date, float date) 5. There is one index on the table: (int, date, date). Is my database corrupt? Will CLUSTER corrupt my tables if it doesn't finish successfully? Thanks. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
