Hello Carlos.


I continue to work in the implementation of the 3.0 protocol in C#, i'm making a test that consist on:

- Create a database.
- Create a table in the new database.
- Start transaction.
- Insert 100 rows of data in the new table.
- Commit transaction.

For start a transaction i send a Query message with this as statement text:

START TRANSACTION ISOLATION LEVEL READ COMMITTED

For commit a transaction i send a Query message with this as statement text:

COMMIT TRANSACTION

For execute the inserts i use parametrized commands with Extended query mode, sending this sequence of messages:

- Parse & Flush ( Only for the first command )
- Describe & Flush ( Only for the first command )
- Close Portal ( begining at second command )
- Bind & Flush
- Execute & Sync

But the Sync message seems to be commiting the transaction, if i send a Flush message all works as expected with inserts, but create database & table will not work.


Sorry for late response...
I could finally get Npgsql to talk protocol 3.0 version :) It is not 100% but it is near...
I give it a try in a test similar to yours... I didn't send the create database commands just the row insertion.


in both sequences, I could get the desired behaviour.
I could send the begin transaction in simple query mode, send the insert in extended mode and send a commit or rollback in simple mode sending the sync message in the end of extended mode.



Are you still having problems with it?


I hope it helps.
