+1 from me, patch applies and is helpful.

After patching this line in psql --help is 82 characters long; I think
it's best to keep help screens below 80 characters wide (although
there's already 1 other line violating this rule).

I think the word "set" is pretty useless there anyway, maybe remove
that so the message becomes "field separator for unaligned output
(default: "|")"

PS: There isn't an open CommitFest to add this to. Shouldn't we always
open a new CF when the last one goes in progress? If there's no date,
it may be simply called "next"

Regards,
Marti

Hi Jov,

A new commitfest was just opened, due on 2014-06. Please add your patch here:
https://commitfest.postgresql.org/action/commitfest_view?id=22

(You'll need a community account if you don't already have one)

Sometimes simple fixes like yours are merged outside a CommitFest, but
adding it there makes sure it won't get lost.

Regards,
Marti

If you are going to change the help string for -F, you should also
update the help string for -R, and possibly for -z and -0.
