while implementing the protocol 3.0 I could get the data in text mode setting the format to 0. (Thanks all for helping me out with flush message)
Now, I want to test the binary format. While some primitive types are easy to realize, for example a int4 field will be encoded in 4 bytes,
I don't know how other types, like date, time, timestamp, text will be encoded in binary format.
Huummmmm i'm going to comment how i make in my C# implementation (stream is a binary reader ) for example for int4, date and time.
For int4:
int val = stream.ReadInt32(); int int4Value = IPAddress.HostToNetworkOrder(val);
For date ( not sure if i'm making this correct way but values seems to be correct :) )
DateTime base = new DateTime(2000, 1, 1) int val = stream.ReadInt32(); int days = IPAddress.HostToNetworkOrder(val);
DateTime date = base.AddDays(days);
For Time:
The same as for date but reading a double and adding it to base as seconds instead of days.
The only basic data type i'm not handling now is numeric that seems to be encoded in 10 bytes but i have no seen the postgre source code yet.
