More information to add to this bug.
I get the same behavior as the original poster, but the following on these
queries:
sszabo=> select myfloat-29.92 from "test_f4";
?column?
----------------------
7.62939436071974e-08
7.62939436071974e-08
(2 rows)
sszabo=> select myfloat-'29.92' from "test_f4";
?column?
----------
0
0
(2 rows)
This is probably due to the float constant being made
a float8 since I also see the following:
sszabo=> select 29.92::float4-29.92::float8;
?column?
----------------------
7.62939436071974e-08
(1 row)

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
