Without seeing the result of the r.dbfilename call it's hard to tell.

  result = pageinfo_tbl.select do |r|
    dbf = r.dbfilename
    re =  Regexp.new(dbf)
    
    if re.match($psfile)
      true
    else
      puts "#{r}.dbfilename => #{dbf} => #{re} which failed to match #{$psfile}"
      false
    end
  end

might tell you something.
