Consider your initial output of \pset, when no option is specified
=================
$ ./psql
psql (11devel)
Type "help" for help.
postgres=# \pset
border 1
columns 0
expanded off
fieldsep not used
fieldsep_zero ERROR
footer on
format aligned
linestyle ascii
null ''
numericlocale off
pager 1
pager_min_lines 0
recordsep '\n'
recordsep_zero off
reset ERROR
tableattr
title
tuples_only off
unicode_border_linestyle single
unicode_column_linestyle single
unicode_header_linestyle single

These entries with ERROR correspond in fact to no error at all,
or we have to pretend that the default state of psql is erroneous,
which doesn't make sense.
Also "reset" is not a variable, it seems to be a command,
so it probably shouldn't be there in the first place.
More generally, I'd think the point of reusing "fieldsep" was to
reuse the concept, not reimplement it, let alone changing
bits of behavior of the unaligned mode along the way.
With this patch, again without specifying any option, just looking
at what fieldsep is leads to this:
postgres=# \pset fieldsep
User didn't specified field separator.
Current format doesn't specify default field separator.
If this is the way to "solve" the fact that a user has to do
\pset fieldsep ','
to get commas in csv mode, then IMV the proposed solution
is clearly worse than the stated problem, and worse than
simply adding fieldsep_csv to be independant from the
unaligned mode.
