Right. It would also increase the cognitive load on the user to have
to remember the command-line go-to-line-number switch for his editor.
So I don't particularly want to redesign this feature. However, I can
see the possible value of letting EDITOR_LINENUMBER_SWITCH be set from
the same place that you set EDITOR, which would suggest that we allow
the value to come from an environment variable. I'm not sure whether
there is merit in allowing both that source and ~/.psqlrc, though
possibly for Windows users it might be easier if ~/.psqlrc worked.
