Newbie question about datatype conversion

I can't seem to figure out how to convert a varchar to a text or a text to char or anything. I've tried doing exactly
asthe good documentation says but this is the kind of response I get.
 

foo=> select orgname from organization;
orgname
----------------------

(2 rows)
foo=> \d organization;
<---SNIP--->
| orgname   | varchar() not null   |    25 |
<---SNIP--->

foo=> select text(orgname) from organization;
ERROR:  function text(varchar) does not exist
foo=> select orgname::text from organization;
ERROR:  function text(varchar) does not exist
foo=> select char(orgname) from organization;
ERROR:  parser: parse error at or near "orgname"
foo=> select orgname::char from organization;
ERROR:  function char(varchar) does not exist

I must be doing something really silly but I just don't see it. Any suggestions? TIA
