Sequences are just a form of a table:

http://www.postgresql.org/docs/9.4/interactive/sql-altersequence.html
"
For historical reasons, ALTER TABLE can be used with sequences too; but
the only variants of ALTER TABLE that are allowed with sequences are
equivalent to the forms shown above."

So I would try the ALTER TABLE .. SET TABLESPACE on them also.
