psql tab completion: \c [ dbname [ username ] ]

Hi

Attached is a mighty trivial patch to extend psql tab completion
for \c / \connect to generate a list of role names, as lack thereof
was annoying me recently and I can't see any downside to doing
this.

The patch is a whole two lines so I haven't submitted it to the next
commitfest but will happily do so if appropriate.

Regards


Ian Barwick
