It is too complex and expensive to lazy create the connection pool because all methods which uses the pool needs to acquire a lock. So it is easier to create it when the instance is also created. In this case, on closing the database, it should be unregistered from the instances dictionary. issue6202 review32991002

Database Backends
-----------------
Tryton is mainly developed for PostgreSQL (8.2 or later) but there are other
backends available. Here are some warnings about using other backends:
* MySQL
* The lock implementation of MySQL requires that Tryton locks all tables.
* There are problems with floating-point comparisons.
See: http://dev.mysql.com/doc/refman/5.5/en/problems-with-float.html
* Tryton uses a VARCHAR(255) for Char, Selection and Reference fields.
* MySQL can not create indexes containing text or blob fields.
* Timestamp has a precision of second which is used for optimistic lock.
* Tryton uses a DECIMAL(65, 30) for Decimal fields and DOUBLE(255, 30) for
Float fields.
* MySQL version should be 5.0 or later.
* SQLite
* SQLite can not alter column definitions nor create foreign keys.
* SQL constraints are validated by Tryton instead of database.
* Timestamp has a precision of second which is used for optimistic lock.
