There are not enough spaces available in the column to allow for the number
of DOC_IDs. There are three spaces, allowing for at most four occurrences
of DOC_ID, but there are eleven. --Rick

It's unclear from just this data, but there's a chance that there are
varying numbers of spaces after 'DOCID', which would appear as separate
values for the index, even though they aren't readily apparent. Could
you show us the results of the following query?
select constname, length(constname) as constname_length
from a_constants_str;
Here's another one which would show if PostgreSQL is treating them
equally:
select constname, count(constname)
from a_constants_str;
The results of these queries might shed some light on the issue.
Hope this helps.
