Without seeing a more complete example, it's hard to say. It works
for me here:
create table real_test
(
real_label text primary key
, real_value real not null unique
);
copy real_test (real_label, real_value) from stdin;
foo 1.2
bar 10.53
baz 10.5
bat -54.3
\.
test=# select * from real_test;
real_label | real_value
------------+------------
foo | 1.2
bar | 10.53
baz | 10.5
bat | -54.3
(4 rows)
test=# select * from real_test where real_value >= 10.5;
real_label | real_value
------------+------------
bar | 10.53
baz | 10.5
(2 rows)
test=# select * from real_test where real_value = 10.5;
real_label | real_value
------------+------------
baz | 10.5
(1 row)
test=# select version();
version
