8.3beta bug or feature?

folks

 the follow queries work in postgres 8.2 but
 in  8.3beta don't work


SELECT c.* FROM c WHERE  c.numero LIKE '1%';

i think automatic conversion of  numeber to text is
the problem , in 8.3beta don't work
numero field is  integer type
any ideas?

 best regards
 mdc

ps:"PostgreSQL 8.3beta3 on i686-pc-linux-gnu, compiled
by GCC gcc (GCC) 4.1.2 (Gentoo 4.1.2 p1.0.1)"
