-'''Multiprocessing test.
-
-PgManager is partially safe against process forking.
-
-You can create connection credentials (create_conn) in main process, then fork
-and continue working with pgmanager in children processes. You can call create_conn again
-in children, but new connection credentials will be accessible only from process
-where it was created -- no sharing between processes.
-
-get_conn and cursor will still work after fork. Connections from parent process will
-be forgotten, that cannot be used un child process. 
-
-Connections cannot be shared between processes, DO NOT:
- * get_conn, then fork, then put_conn
- * get_conn, then fork, then use the connection, then .close()
-
-Good usage:
- * create_conn, fork, get_conn, cursor, etc.
-
-Basically, you can transfer only information from create_conn(), nothing else.
