Erik JohnstonandClaude Fable 5.1 7d86758f01 Retry transactions whose cached plan went stale on the Rust backend ...

The Rust backend prepares and caches statements per connection. DDL that
changes a cached statement's result type, such as a schema delta applied
during a rolling restart, makes Postgres reject the stale plan with
SQLSTATE 0A000. Inside a transaction that error used to propagate as a
plain DatabaseError, which `new_transaction` does not retry, so other
workers saw transient failures until their caches turned over.

The cursor already drops the cached entry before the error propagates,
so treating 0A000 like a deadlock means the retried transaction prepares
a fresh plan.
