rounded floats produce an error

[sunneach]

I had to supply missing ".0" to some rounded floats to avoid errors. Here is the patch:

pgsql_util.erl, line 267:

decode_col(#desc{format=text, type=Float}, Value)
when Float =:= float4; Float =:= float8 ->
ListValue = binary_to_list(Value),
IsFloat = string:str(ListValue,"."),
if IsFloat > 0 -> FValue = Value;
true -> FValue = Value ++ ".0"
end,

list_to_float(FValue);
