You could also use describe (in psql environment )
psql mydatabase
mydatabase=# \d indexname
Index "indexname"
Attribute | Type
------------+---------------
fieldname | datatype
unique btree
The word "unique" will show up only if the index has the unique
qualification, otherwise it will read only "btree".
Hope this helps.
