I've been making some tests with emacs shell mode, and it seems less does
not work ( expected ) and more works partially ( it seems in shell mode
emacs does whole lines only, so \040 does not work ). The ONLY problem I
see with psql is that the more/less usage as default pager seems to be
undocumented ( I mean, I have not bien able to find it without resorting to
the source code ). My problems with emacs seem to be caused by my actions,
that is, invoking a program which needs a minimally smart terminal inside a
really dumb one, and are easily solved by not doing it ( by the existing
mechanism of psetting pager to off, which I think is easy enough for
someone who uses psql inside emacs shell buffers, as he must be familiar to
the problems with any terminal controlling program ) . Psql source is hairy
enough cattering for windows/*ix stuff, and anyone can write a wrapper to
test for the INSIDE_EMACS and invoke psql with the appropiate pset option.

And the psql interactive shell is not a joke, it is a big chunk of the
reasons why I use postgres.

Just my opinion / vote.
