I'll mention that psycopg2, the most widely Python DBI implementation for PostgreSQL, has a built-in mapping of hstore to dict, so signs are definitely pointing towards a hstore == dict standardization. It also suffers from the problem that it needs to sniff the hstore OID, which is somewhat annoying, especially in a web environment where the sniff has to happen repeatedly.
