There are a couple of TAP tests where the copy binary is expected to fail. And when it fails, you do binary=false (changing the format back to 'text') so the test is then expected to be able to proceed.
I don't know if this happens in practice, but IIUC in theory, if the timing is extremely bad, the tablesync could relaunch in binary mode multiple times (any fail multiple times?) before your binary=false change takes effect. So, I was wondering if it could help to use the subscription 'disable_on_error=true' parameter for those cases so that the tablesync won't needlessly attempt to relaunch until you have set binary=false and then re-enabled the subscription. ------ Kind Regards, Peter Smith.
