On the whole I'd rather not eat more of the limited namespace for

It depends on personal preferences. When I work on a large screen, I can
afford to spend some characters in prompts, if it gives convenience –
and many do (looking, for example, at modern tmux/zsh prompts showing
git branch context, etc).
Default behavior might remain short – it wouldn't make sense to extend
it for everyone.
I have no objections to adding a %T option, although deciding what
format to use is a hassle. -1 for changing the default.
But let's look at the original request:
This has been in sqlplus since I can remember, and I find it really
useful when I forgot to time something, or to review for Time spent
on a problem, or for how old my session is...
I've felt that pain too. You run a query, and it takes longer than I
expected. How long did it actually take? Too bad I didn't enable \timing
beforehand..
How about a new backslash command or psql variable to show how long the
previous statement took? Something like:
postgres=# select <unexpectedly slow query>
?column?
----------
123
(1 row)
postgres=# \time
Time: 14011.975 ms (00:14.012)
This would solve the "I forgot to time something" problem.
