Hi! 

is there a function in postgres that can be used to retrieve unique
attribute values from an array?

I retrieved the attributes and their values from a class using PQgetvalue()
function and stored them in an array. The values have duplicates in them
and i want to retrieve unique values. Any function in postgres which does that?

Thanx in advance.
