That is what my patch does: it tests prompts, tab completion, help,
command options… and I added tests till I covered most psql source.
Well, I think that where possible we ought to test using the existing
test infrastructure -- help, for example, seems like it could perfectly
well be tested in src/test/regress/sql/psql.sql, or we could move stuff
out to a new set of SQL test scripts under src/bin/psql/sql/,
I do not think it is a good idea, because help output is quite large,
there are many of them, and we should certainly not want it stored
repeatedly in output files for diffs. I rather trigger the output and only
check for some related keywords, so that it fits TAP tests reasonably
well.
