I've created a patch which adds support for troff "-ms" output to
psql. i.e. "\pset format troff-ms". The patch also corrects some
problems with the "latex" format, notably defining an extra column in
the output table, and correcting some alignment issues; it also
changes the output to match the border setting as documented in the
manual page and as shown with the "aligned" format.
The troff-ms output is mostly identical to the latex output allowing
for the differences between the two typesetters.
The output should be saved in a file and piped as follows:
Because it contains tabs, you'll need to redirect psql output or use
"script", rather than pasting from a terminal window, due to the tabs
which can be replaced with spaces.
