No, the point is that I usually have mixed queries -- ones which are
most comfortably viewed in normal format (many not-so-long rows),
and ones which are best viewed expanded (little rows, many columns).
Alternating between formats using "\x" is, at least for me, a bit
cumbersome: usually _after_ I wrote a query I realize "it would
look more readable in expanded format", which is a bit too late.
So I run the query, ctrl+c, \x, rerun the query... and forget to
turn expanded mode off afterwards.
I think that ability to decide about the format after the query,
not before, can be quite useful especially when writing ad-hoc
queries. Incidentally "\g" and "\G" is also used more or less
similarily by our dolphin-loving friends -- which doesn't help
using "\G" for other things.
