is there a way to configure psql/readline so that it doesn't clear the screen after browsing a query with 'q'? regards, merlin

You don't say the OS, but you may be seeing the effects of less working on a terminal with a seperate interactive screen (for example xterm). What's happening is that when less exits, it switches back to the main screen, thus hiding what you were just looking at. From reading the manpage, setting the pager to "less -X" should solve this problem.

Assuming you are using less as your PAGER, then see: http://www.greenwoodsoftware.com/less/#tite One can add the -X option to your LESS or PAGER environment variables. -M

I like the following invocation: less -iMSx4 -FX (see less manpage for explanation). This is particularly useful with ' \pset pager always' (in .psqlrc). The upshot is that less will decide whether the contents fit on one screen both horizontally and vertically; if so it'll display and quit without any interaction, and if not it will permit scrolling in one or both directions.
There are two ways you might enable this:
- set and export the LESS environment variable in your shell setup, like this in .bashrc:
export LESS='-iMSx4 -FX'
- prefix your psql invocation with the LESS environment variable setting, like this:
$ LESS='iMSx4 -FX' psql <optargs...>
