This is the responsibility of the class which encapulates the
connection (its instances are used as values of the "_v_connection"
attribute) if it does not happen automatically.

It happens automatically for ZPsycopgDA.

It happened automatically for an ancient ZOracleDA version (I used
several years ago) after I had prevented the creation of
a cyclic structure (which prevented automatic garbage collection).
