Also available in: Unified diff
schemas/util.sql: added hstore(keys text[], value text), which can be used to avoid repeating the same value for each key. there are many /_map filters which use the XPath syntax for doing this, which now need to use an equivalent SQL syntax to avoid duplicating the value many times.
