Database.PostgreSQL.Simple.HStore

Parsers and printers for hstore, a extended type bundled with PostgreSQL providing finite maps from text strings to text strings. See https://www.postgresql.org/docs/9.5/static/hstore.html for more information.

Note that in order to use this type, a database superuser must install it by running a sql script in the share directory. This can be done on PostgreSQL 9.1 and later with the command CREATE EXTENSION hstore. See https://www.postgresql.org/docs/9.5/static/contrib.html for more information.
