Can't reproduce it here. Anyone else seeing this?

If you do something like
COPY int4_tbl TO 'int4out';
you will get the file dumped into the database directory, because that
is the current working directory of the backend; you need to give a
full path in this form of the COPY command to get the file put someplace
more useful. But I don't see how COPY could produce two output files
when it's only doing one fopen()...

It occurs to me that it's a very dangerous thing for server-side COPY
to default to storing into the DB directory; pick the name of an
existing table and boom, you just overwrote your table. Maybe the
server-side COPY command ought to insist on being given an absolute
path?
