Based on this strong positive response and adoption during the beta, we're officially moving these plans to general availability starting today.
In conjunction with the GA of our starter tier, we're deprecating our shared database plans. The new dev and basic plans offer many improvements including Postgres 9.1 with schemaless SQL, data clips, direct psql access, and a web management interface.
Beginning August 8, 2012, we will begin migrating shared database users over to the new starter tier. Users may control their application down time by migrating their databases ahead of August 8.
