The easiest way to deal with this, is, as the "postgres" user:
1. Change to the location of the datafiles, which, for a
database, called "mydatabase" will look something like:
cd /usr/local/pgsql/data/base/mydatabase
2. Create an empty file of the name of the index:
touch user_usage_email_idx
3. Delete the file using psql:
psql mydatabase
> DROP INDEX user_usage_email_idx;
4. Recreate the index as appropriate
Hope that helps,
