That parameter was added in 7.0. The 6.x version of db.select always
writes to stdout.
You can just run db.select using grass.script.pipe_command(), e.g.:
import grass.script as grass
ps = grass.pipe_command(
'db.select',
quiet = True,
flags = 'c',
table = table,
sql = sql)
for line in ps.stdout:
fields = line.strip().split('|')
...
ps.wait()
