pg_dump and psql disagree on numerical precision (powerpc) - Mailing list pgsql-bugs

I didn't believe it at first:

create table test ( x double precision);

insert into test values (0.3);

test=# select * from test;
   x
-----
  0.3

-- Data for TOC entry 3 (OID 53248)
-- Name: test; Type: TABLE DATA; Schema: public; Owner: christof

COPY test (x) FROM stdin;
0.29999999999999999
