A tough version of the connection constructor of a DB-API 2 module.
creator: either an arbitrary function returning new DB-API 2 compliant
connection objects or a DB-API 2 compliant database module
maxusage: maximum usage limit for the underlying DB-API 2 connection
(number of database operations, 0 or None means unlimited usage)
callproc(), execute() and executemany() count as one operation.
When the limit is reached, the connection is automatically reset.
setsession: an optional list of SQL commands that may serve to prepare
the session, e.g. ["set datestyle to german", "set time zone mez"]
failures: an optional exception class or a tuple of exception classes
for which the failover mechanism shall be applied, if the default
(OperationalError, InternalError) is not adequate
ping: determines when the connection should be checked with ping()
(0 = None = never, 1 = default = when _ping_check() is called,
2 = whenever a cursor is created, 4 = when a query is executed,
7 = always, and all other bit combinations of these values)
closeable: if this is set to false, then closing the connection will
be silently ignored, but by default the connection can be closed
args, kwargs: the parameters that shall be passed to the creator
function or the connection constructor of the DB-API 2 module
