My summary was incomplete. The --csv option implementation by Daniel
already does that.
The issue Pavel is complaining about is that in interactive mode "\pset
format csv" does not do the same: it triggers the csv-rule string-escaping
mechanism, but does not reset the "fieldsep" variable (eh, it sets the
"format" variable) so the default separator under this interactive use is
"|" if the "fieldsep" variable is shared.
I have suggested a "\csv" interactive command to set both as a convenient
shorthand for "\pset format csv & \pset fieldsep ','", similarly to --csv,
but Pavel still wants "\pset format csv" to trigger the full csv output.
A consequence I forgot about adding "fieldsep_csv", is that it probably
has to duplicate the "_zero" ugly hack to be consistent with existing
"*sep" variables, or else be inconsistent. Sigh.
