Your memory is playing tricks on you. That behavior is the same as it
ever was (or at least, the same as it was back to 7.0, the oldest
version I have handy to try your example on).

regression=# create table test ( test character(200) );
CREATE
regression=# insert into test values ('test(at)test(dot)com');
INSERT 797819 1
regression=# select * from test where test = lower('TEST(at)TEST(dot)COM');
test
------
(0 rows)

regression=# select version();
version

PostgreSQL 7.2.3 on hppa-hp-hpux10.20, compiled by GCC 2.95.3

Convert. char(n) is evil. If I had my druthers, we'd take it out
of the language.
