The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/9.5/ssh-tunnels.html Description:
"The first number in the -L argument, 63333, is the port number of your end of the tunnel; it can be any unused port. (IANA reserves ports 49152 through 65535 for private use.) The second number, 5432, is the remote end of the tunnel: the port number your server is using. " as a beginner This took me some time to understand what do you mean by "your server" "your end of the tunnel "
