You can't use single quotes. Instead, use double quotes.

$ psql -q
euler=# create temp sequence 'rateSeq';
ERROR:  syntax error at or near "'rateSeq'"
LINE 1: create temp sequence 'rateSeq';
                             ^
euler=# create temp sequence "rateSeq";
euler=# select relname from pg_class where relname ~ 'rate';
 relname
---------
 rateSeq
(1 row)

Temporary relations can't be dropped in another session. However, the
temp sequence will gone away when you close the connection that created it.

If you want to run your script many times in the same session, make sure
you include a DROP SEQUENCE at the end of the script.
