pl/pgsql is new in 6.4. If you are working with 6.3.2, you may define a
function in SQL as follows:

testing=> CREATE FUNCTION text( float8 ) returns text
testing-> AS 'select textin( float8out( $1 ) )'
testing-> LANGUAGE 'sql';

Test this:

testing=> select text( 18.4 ) || ' is the number';
?column?
------------------
18.4 is the number
(1 row)
