Here is a patch that does just that, while maintaining the

"traditional" behavior, so the change should be transparent. Use the
command "\pset pager always" to turn it on. Anything else does the
normal toggle between "on" and "off"

<para>
In any case, <application>psql</application> only uses the
pager if it seems appropriate. That means among other things
that the output is to a terminal and that the table would
normally not fit on the screen. Because of the modular nature
of the printing routines it is not always possible to predict
the number of lines that will actually be printed. For that
reason <application>psql</application> might not appear very
discriminating about when to use the pager.
When the pager is off, the pager is not used. When the pager
is on, the pager is used only when appropriate, i.e. the
output is to a terminal and will not fit on the screen.
(<application>psql</> does not do a perfect job of estimating
when to use the pager.) <literal>\pset pager</> turns the
pager on and off. Pager can also be set to <literal>always</>,
which causes the pager to be always used.
