col = $n bound to NULL never matches in sql, so get/get_one/exists/delete
silently missed every row filtered on a None value despite insert() writing
NULL fine. Kept in lockstep with the mysql lib's identical fix.

connect() now closes an existing pool before re-connecting (no orphan on double-connect),
and tears down the freshly-built pool if the SELECT-1 validation fails before re-raising
(no leaked pool on a failed connect). verified vs embedded postgres. bump v0.1.1 -> v0.1.2

_Transaction.__aenter__ acquired a connection then called tx.start(); if start() raised
(stale pooled conn after failover/idle-timeout — a fail-loud path), __aexit__ never ran so
the connection leaked, draining the pool until transaction() deadlocked on acquire(). now
release-on-failure. verified: 6 forced start-failures (2x pool) no longer exhaust the pool.
bump v0.1.0 -> v0.1.1
