I'm guessing this is because 0.1 is not directly representable as a binary floating point number, and literal floating constants are float8 not float4, and 0.1::float4 != 0.1::float8. Same problem that causes queries on int2 fields not to use an index unless you cast the constants in the query... -Doug ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
