Add two IO wait events for COPY FROM/TO on a pipe/file/program Two wait events are added to the COPY FROM/TO code: * COPY_FROM_READ: reading data from a copy_file. * COPY_TO_WRITE: writing data to a copy_file.
In the COPY code, copy_file can be set when processing a command through the pipe mode (for the non-DestRemote case), the program mode or the file mode, when processing fread() or fwrite() on it.
