        Hello,

        I'm moving a MySQL database to PostgreSQL and redesigning parts
        of it to
        take advantage of PostgreSQL's richer type system and other advance
        features. Currently I am attempting to replace a table of name/value
        pair data w/ a hstore column. But now that the data will no
        longer be
        flattened out in a table I need to manually handle referential
        integrity

The benefit is supposed to be client side simplicity. The data in these
particular tables are ultimately consumed by JavaScript as JSON on the
front end to populate/maintain a dynamic HTML for​m. So I was attempting
to build a model that more closely reflects how the data is used because
the people using the data aren't SQL folks and the code that converts
the data from table/rows to JSON is not straight forward for my audience.

In that case you may want to look at the JSON types, json and/or jsonb(depending on Postgres version):
