Hi,

I recently stumbled over an issue with an unintentional re-transmission. 
While this clearly was our fault in the output plugin code, I think the 
walsender's exposed API could easily be hardened to prevent the bad 
consequence from this mistake.

Does anything speak against the attached one line patch?

Best Regards

Markus
