Yes, sorry for having lost the original thread, my mailbox has a quite 
stupid automatic purge schedule...

The script is run in a windows batch file.
Basically, export.bat contains :

SET PGUSER=myuser
SET PGPASSWORD=mypwd
SET PGCLIENTENCODING=UTF8
SET MYPGSERVER=myserverurl
SET MYPGDB=mydatabase
psql -h %MYPGSERVER% -a -f myscript.sql %MYPGDB%

And myscript.sql contains :
\copy (SELECT * FROM view1) TO '\\server\share\view1.txt'
\copy (SELECT * FROM view2) TO '\\server\share\view2.txt'
...
etc with ~60 views

Today, I've update the problematic \copy line to be :
COPY (SELECT * FROM view) TO STDOUT \g '\\server\share\view.txt'

I'll keep you informed (even though a successfull run is not a guarantee 
of success, because the original script did sometimes work).
