Ugh. This seems like a rather fundamental oversight in the CSV feature.
The problem is that psql has no idea whether the copy is being done in
CSV mode or not --- and even if it did, it doesn't parse the data fully
enough to realize whether a \. line is inside quotes or not.
In the case of out-of-line data files, it might be reasonable to just
dispense with the check for \. altogether and always ship the whole file
to the backend; I think there's a \. check on the backend side. (Not
sure this is safe in V2 protocol, but I doubt anyone cares anymore
about that.)
In the case of in-line data in a script file, CSV mode seems a bit
broken in any case; there's no concept of a terminator in CSV, AFAIK.
So maybe we don't have to worry about that.
