Hi,
I've just added the hstore_get_value() to both OGR SQL and SQLite dialects.
This can be especially useful with the OSM driver to extract values associated
to a key from the other_tags attribute that has a HSTORE formatting (
http://www.postgresql.org/docs/9.0/interactive/hstore.html )
From the doc:
"""
Starting with OGR 2.0, the hstore_get_value() function can be used to extract
a value associate to a key from a HSTORE string, formatted like
"key=>value,other_key=>other_value,..."
SELECT hstore_get_value('a => b, "key with space"=> "value with space"', 'key
with space') --> 'value with space'
"""
