NameError: global name '_' is not defined when unable to get database connection from pool

It looks like there is a missing import in the db pooling code:

I discovered this as well some days ago, and have already fixed it in [7455] - unfortunately not spotted until after 0.11.1 release.

As I fixed it without a ticket, this ticket may serve well as a reminder for the bug fix againt the 0.11.2 milestone.
