| Hi all, I have a question (or more of a guidence request) in regards to PostgreSQL v8.4 Protocol v3 and accessing the database via TCP. Background: part of the summer project that Im involved in I have to create fast & light (open connection, send query, read results) .Net 4 (C#) provider, similar to npgsql but should only use streams. So far I managed to get socket connection to database and authenticate (recived AuthenticationOk response code from database), right now Im not shure what to do. Documentation says that I need to wait for other messages from the server, such as "BackendKeyData" or "ReadyForQuery" but the database is not writing anything into a buffer so when I try to read from it, my application just waits. So question is after I recive AuthenticationOk, do I need to wait for ReadyForQuery message from the database or I can go ahead and start senting queries to the database? Database: PostgreSQL v8.4 Aplication Platform: .Net 4.0 Protol Documentation: http://www.postgresql.org/docs/8.4/interactive/protocol.html Thanks. PS: A have been looking at the source code for Npgsql, but I can't make sence of whats going on. |
