I wish arrays and hstore-like types were available in sqlite (not through plugins, but standard-wise).
I've used something else from my experiments in PostgreSQL - the TXID - this way I was able to track down changes in the database (by keeping previous TXID and some other various bits, and then by polling again (or making the server call me)) - polling again and only instructing to get the rows that have changed since my last TXID.
