Don't do that. those files are managed by Postgres so you may finish
with a corrupted cluster. Instead you should lower the value of

wal_keep_segments, reload the server parameters, and then enforce two
checkpoints to force WAL segments to be recycled. Note that this

depends also on the values of checkpoint_segments
(max_wal_size/min_wal_size in Postgres 9.5 and onwards).
