I'd like to report a bug in 7.1.3 psql (at least on a 64-bit Alpha Linux box).
Maybe someone can confirm this or maybe it's fixed in 7.2
The 7.1 documentation ( http://www.postgresql.org/idocs/index.php?sql-copy.html )
for COPY ala
COPY table FROM 'filename'
says that if it fails you get feedback "ERROR: reason" and if it succeeds
you get feedback "COPY". However, I goofed today and my filename was a
directory, and I did not get ERROR... Here is a simplified version
demonstrating the lack of ERROR:
