Not sure why the single quotes are getting stripped out but that is the
issue. Maybe double them up to escape them like in a normal text literal?
Otherwise consider just doing a comma delimited string and using
string_to_array in the sql to turn it into an array at runtime.

Not with \set. You could write sql to output the text and then execute it
using \gexec to store the column value in a variable. That too may be a
solution to the missing single quotes.
