Then I'm confused:
regress=> create table test (x numeric);
CREATE TABLE ^
regress=> insert into test (x) values ('3');
INSERT 0 1
regress=> insert into test (x) values ('3.0');
INSERT 0 1
regress=> insert into test (x) values ('3.00');
INSERT 0 1
regress=> insert into test (x) values ('3.000');
INSERT 0 1
regress=> select * from test;
x
-------
3
3.0
3.00
3.000
