  -- 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.
