Обсуждение: postgresql data structure

Ahoi. I had to write a lightweight small utility to connect to a
postgreSQL dbase.
My question is: where can i find detailed data on the structure of the
data sent during a simple session (for example identify, query, get
response from server, logout) from client to server?
Thanks

I think you are looking for the protocol spec:
