Hello
How can we generate in the log of executed querys (directory pg_log) the
amount of bytes transferred between the server and the client of the result
of a query?
Example:
a) select now (); - few bytes transferred
b) select * from large_table; - 20,000,000 bytes transferred
I understand that this parameter can reduce the performance of the database
in general. I intend to use this information to measure the impact of each
query on the total volume of bytes transferred by the network interface by
IP address in a log analysis tool such as pgBadger
