pager
Controls use of a pager program for query and psql help output. If the environment variable PAGER is set, the output is piped to the specified program. Otherwise a platform-dependent default (such as more) is used.--

If you use less for pager and want this behaviour system-wide, you'll want to set another env variable: setenv LESS -X (I use tcsh) or export LESS=-X if you use bash.

That makes less behave properly (not clearing the screen) after closing man-pages and such.
