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)"
