have anyone replicated data from a postgres DB using an ssh tunnel to connect? none of the singer taps listed on the hub seem to support this

You should manage SSH on the OS level a vast majority of the time. There is little benefit to bundling that into the tap ssh <name>@<server_ip> -L <localPort>:<127.0.0.1 or remote host if using jumpbox>:<remotePort> Exclusively in meltano, I would imagine a utility plugin that interpolates the shell command for the ssh invocation

https://gitlab.com/meltano/meltano/-/issues/3501 I don't have a fix listed here, but I think @alexander_butler is on it! A utility plugin would be pretty slick here I think

oh yeah a utility plugin would be cool!
