That means that PostgreSQL is reading a file that it wants to copy to
another file, and it it waits for the read operation to finish.
If you are stuck on this for a long time, perhaps you have a file on a
networked file system, and the network connection went bad.
It is hard to say more without knowing what your query is and where the
file resides.
