float4 problem

May be I miss something, but seems there is a problem with float4
in 7.2.3 and 7.3RC1 (6.53 works fine):

test=# create table t ( a float4);
CREATE TABLE
test=# insert into t values (0.1);
INSERT 32789 1
test=# select * from t where a=0.1;
a
---
(0 rows)

test=# select * from t where a=0.1::float4;
a
-----
0.1
(1 row)

No problem with float8

test=# create table t8 ( a float8);
CREATE TABLE
test=# insert into t8 values (0.1);
INSERT 32792 1
test=# select * from t8 where a=0.1;
a
-----
0.1
(1 row)

Regards,
Oleg
