Because PostgreSQL still has access to all the significant digits:
test1=3D# SELECT f FROM t WHERE id =3D 1;
f
-----------------
5.63219288e-032
(1 row)
Since floats are stored with a significand and an exponent, to_char()
should be able to convert 5.6e-32 to text just as easily as it can
convert 5.6e-3. For some reason, it doesn't.
