* DEV: upgrade mini_sql Even though we are not planning on using this quite yet, mini_sql now supports prepared statements. Would like this upgrade merged so we can do some benchmarking. Note, this will not work with pg_bouncer, but sites that are not using it may benefit from the feature. * implement multisite friendly prepared statements
