Description:

I never want to use the pager, as it comes up at the most inopportune times
in Emacs shell-mode, so I have configured my ~/.psqlrc with:

\pset pager off

This works for psql -f <script>.psql. However, when I run one-off commands
with psql -c <command>, the pager pops up again, making psql -c really hard
to use in my Emacs workflow.
