Query doesn't work anymore on 7.2

Hello there. I've just upgraded to pgsql 7.2 on netbsd and one of my programs stopped working because of a parser error:

carteirinhas=# \d registros
Table "registros"
Column | Type | Modifiers
-----------+------------------------+-----------
matricula | integer |
resp | character varying(50) |
tipo | character(1) |
nome | character varying(50) |
data | date |
hora | time without time zone |
baixa | boolean |

carteirinhas=# insert into registros values (1234,'Teste','A','Teste',date('now'),time('now'),false);
ERROR: parser: parse error at or near "'"

Although it's clear that this program was done in 10 minutes, it was working on 7.1.3. Has something changed or it seems to be a bug in 7.2's parser?
