Fix verbose configuration option value check

[stephane]

This commit corrects the check for the 'verbose' configuration option value. Previously, it was checked if the value was strictly greater than 0, but the use of '-v' flag sets the value to 0.

Edit: My original patch changed to verbose = config.getoption("verbose") >= 0 in fixtures.py.

May be the right fix is to change the message "(add -v option to show queries)" to "(add -v -v option to show queries)"

but the use of '-v' flag sets the value to 0.

I may be confused but I'm pretty sure passing -v sets verbosity to 1, not 0. If so, then the current code is correct. Perhaps you are passing -q somewhere? A -q reduces the verbosity by 1, so -q -v ends up 0.

I didnt use other flags...

Maybe it's in your pytest config or in PYTEST_ADDOPTS envvar.
