Feature #4854

Updated by Juliana Fajardini Reichow 10 months ago

When the postgresql backend sends or receives the following commands: 
 - "COPY FROM STDIN" 
 - "COPY TO STDOUT" 
 It enters the COPY subprotocol-state, subprotocol, which comprises a different set of messages. 

 Currently, if Suri has the pgsql app-layer enabled and sees one of those messages, it doesn't know what to do and stops parsing pgsql messages from that flow altogether, afterwards.
