Bonjour Daniel,
Currently popt->topt.fieldSepCsv can't be NULL so I've simplified this
to just return pset_quoted_string(popt->topt.fieldSepCsv).
Ok.
While testing I found a small issue if "fieldsep_csv" is set to a strange
value:
\pset format_csv ',,'
You meant \pset fieldsep_csv ',,'
Indeed.
If you do that even SELECT 'foo', 'bar' comes out wrong because it looks
like a 3-field row: foo,,bar
Yes and no. I asked for ",," as a separator, so probably I really want
that and I'd be okay with the result.
If we want to prevent people to shoot themselves in the foot with that
sort of thing, I've added a couple tests: No double quote, no LF or
CR, single character (but multibyte allowed) for the separator.
Ok, why not.
Patch applies cleanly, compiles, "make check" ok.
I tried "\pset fieldsep_csv '\0'" which could be seen as one character,
but it does not want it. I'm okay with this behavior.
I'd suggest to add a test about rejected fieldsep_csv values, which raises
both errors.
