Detailed Description

Generator for persistent classic PyGreSQL connections.

After you have created the connection pool, you can use
connection() to get thread-affine, steady PostgreSQL connections.

Constructor & Destructor Documentation

__init__()

def aestate.opera.DBPool.persistent_pg.PersistentPg.__init__	(		self,
			maxusage = None,
			setsession = None,
			closeable = False,
			threadlocal = None,
		*	args,
		**	kwargs
	)

Set up the persistent PostgreSQL connection generator.

maxusage: maximum number of reuses of a single connection
    (0 or None means unlimited reuse)
    When this maximum usage number of the connection is reached,
    the connection is automatically reset (closed and reopened).
setsession: optional list of SQL commands that may serve to prepare
    the session, e.g. ["set datestyle to ...", "set time zone ..."]
closeable: if this is set to true, then closing connections will
    be allowed, but by default this will be silently ignored
threadlocal: an optional class for representing thread-local data
    that will be used instead of our Python implementation
    (threading.local is faster, but cannot be used in all cases)
args, kwargs: the parameters that shall be used to establish
    the PostgreSQL connections using class PyGreSQL pg.DB()
