I suggest upgrading to at least PostgreSQL 9.5 if you haven't already and
look into the INSERT...ON CONFLICT feature (also called UPSERT). With it
you can define what happens if an insert would violate a defined constraint
and instead update the given row, do nothing or a wide variety of other
operations.

https://www.postgresql.org/docs/current/static/sql-insert.html

If this doesn't fit the model that is causing your duplicate key errors,
you may want to look into using a function to do your writes instead and
catch the given error in an exception block and then just ignore it.
