Introduce transaction_joinable flag to mark that the fixtures transaction can't joined, a new savepoint is required even if :requires_new is not set. Use :requires_new option instead of :nest. Update changelog.

[#383 state:committed]

- Fixed compatibility with the old 'postgres' driver which doesn't support
  transaction state introspection.
- Added unit tests for it.

Rename ActiveRecord::Base#transaction's :force option to :nest. Improve documentation for nested transactions.

- also clean up some cruft remaining from per-thread connection cache

Remove CachedConnectionPerThread per-thread pooling mechanism in favor of a fixed pool with default maximum of 5 connections

Previously this would have committed the transaction but not carried out save or destroy operation.

* TestCase: introduce declared setup and teardown callbacks. Pass a list of methods and an optional block to call before setup or after teardown. Setup callbacks are run in the order declared; teardown callbacks are run in reverse.  [Jeremy Kemper]
