Yep, you should definitely and explicitely close database connections.
 Failure to do so can easily leave connections open and resources
locked - not much unlike closing your ssh sessions by killing the
client rather that logging out.

Kind of a coincidence my seeing this email actually - just two minutes
ago I read an email from a team member instructing others on the team
to close their database connections (php/db2) because some connections
occasionally hang and interfere with our loads.
