Interestingly, PostgreSQL 9.2 has regressed here. Not sure if we care,
but worth mentioning:

How did you get that? I don't believe it's possible in the default
output format.
Oh I see, it's because I have \x auto in my .psqlrc. If I set \x auto

How elegant. :-(
Let's see what EnterpriseDB produces:
