Hi Anthonin,

Thanks for the updated patch.

I have noticed this code added in XLogFindNextRecord in the patch, 
appears also in XLogNextRecord (line 334).

> +	if (state->errormsg_deferred)
> +	{

In XLogNextRecord, right before the above code, we do *errormsg = NULL. 
Should this be done also in XLogFindNextRecord in the patch?

If so, what about even extracting a helper method which will be called 
from both places?

A nit for the commit message: Propage -> Propagate

Thanks,
Mircea Cadariu
