assert "database connection" in error

(just kidding)

I was really just leaving as much of the OP's code unchanged as seemed
useful.  Maybe they *want* to print that (possibly inaccurate) message
and return False (from what appears to be module-level code at that!)

FWIW, if I wanted the code to keep going but still report the exception
I would use the logging module's exception() method.  But that seemed a
lot to explain.

You'd get the same traceback printed out either way, but the generic
except statement with the possibly inaccurate message does seem naive
to me.  However, it's entirely possible that the OP *would* like the
code to keep running despite any exceptions while trying to connect to
the db.  In that case, using traceback (or logging) is (IMHO) a
reasonable way to do that but still find out what went wrong.
