Please see the README on GitHub at https://github.com/simspace/postgresql-ltree#readme

postgresql-ltree

Haskell support for PostgreSQL's ltree.

postgresql-ltree

Core types and functions for use in Haskell code. Does not provide support for any database library; use one of the following libraries instead.

postgresql-simple-ltree

Contains type class instances for FromField and ToField for use with postgresql-simple. Re-exports types and functions from postgresql-ltree so there should be no need to depend on both.
