Re: VARCHAR to TIME

oss=> \d test1
Table "public.test1"
Column | Type | Modifiers
--------+-----------------------+-----------
time | character varying(10) |

oss=> select * from test1;
time
----------
03:23:21
(1 row)

oss=> select time::TEXT::INTERVAL from test1;
time
----------
03:23:21
(1 row)

Provided you know all values will be of interval type the above will
work for you.
