Re: Permission denied in file_fdw (Windows)

Hi Thomas

Works like a charm no with different file path.

Thanks for the hint. Did'nt think of that - and I agree with this
implementation decision.
You are referring to RTFM below: May I dare to say that this is not
mentioned in the - otherwise good - docs?

Ack. But let me object that from a readers view the sentence from the
docs "Data files must be in a format that can be read by COPY FROM;
see COPY for details." refers to the format of the file - not to the
syntax of the parameters (strictly speaking :->).

Yours, S.
