Hi all.
It is a great pleasure to say that finally the Npgsql implementation of postgresql protocol 3.0 code is in cvs.
Npgsql is a postgresql .net data provider which works on Mono, portable.net and ms .net implementation.
This code will allow us to benefit from the new features of the protocol, as better handling of parameter types, table description, server version and binary transfer of data without have to use a binary cursor.
This protocol will also allow a better implementation of NpgsqlDataReader as we will be able to retrieve data in a chuncks of rows, (i.e: 30 rows at time) without have to use server side cursor as now you can specify in the protocol how many rows to be returned before Npgsql have to send another request to get the remaining rows.
Another new feature is the binary datatype support. While this isn't yet blob support, you can insert and retrieve binary data which use bytea data type in the server. The type is supported through the DbType.Binary enum value.
Another thing to note is that users using postgresql 7.3 or earlier will notice in log the message "invalid protocol version" messages when using Npgsql. This is caused by Npgsql because it tries first to connect using the 3.0 protocol and falls back to 2.0 if not successfull.
Please, grab the latest cvs code and give it a try. (http://gborg.postgresql.org/project/npgsql)
And please report back any problems you have as well as comments, suggestions and bug fixes :)
Synchronization to the Mono code base will happen soon.
Thanks all for attention.
