But wait ... is it actually a variable?  help.c does list it, but
as a \pset option:

    HELP0("  \\pset [NAME [VALUE]]   set table output option\n"
          "                         (border|columns|csv_fieldsep|display_false|display_true|\n"
...

Some kind of mechanical cross-check does seem like a good idea,
even if it's just a rough one-time effort.

Commits

  1. Refer readers of \? to "\? variables" for pset options

  2. Have psql's "\? variables" show csv_fieldsep

  3. Add CSV table output mode in psql.
