Are you using 7.4? If so:
select split_part('/help/support/index/time.jsp','/',2),
split_part('/help/support/index/time.jsp','/',3),
split_part('/help/support/index/time.jsp','/',4),
split_part('/help/support/index/time.jsp','/',5);
split_part | split_part | split_part | split_part
------------+------------+------------+------------
help | support | index | time.jsp
(1 row)
See:
http://www.postgresql.org/docs/current/static/functions-string.html
On Postgres 8.0.0beta1 you could also do:
select s.f[2], s.f[3], s.f[4]
from (select string_to_array('/help/support/index/time.jsp','/') as f)
as s;
f | f | f
------+---------+-------
help | support | index
(1 row)
