Hi,
I am attempting to copy the contents of a table to a file, like this:

foodserver=> COPY company TO '/home/peter/copytest.out';

But I keep getting this error:

ERROR: COPY command, running in backend with effective uid 100, could not
open file '/home/peter/copytest.out' for writing. Errno = Permission
denied (13).

Does anybody know how I can fix this so I have permission to open files?

Thanks,

Tyler Wood

Use \copy in psql or do it yourself from within
a program. COPY tells the database server to
copy the data, which may not even be on the
same machine...

It's using the backend permissions, which probably can't
write anywhere. Use \copy and be happy...

Make allow access to '/home/peter' for user #100
Or better make in your home something like:

$ cd /home/peter
$ mkdir sql
$ chmod 777 sql

and after this make

foodserver=> COPY company TO '/home/peter/sql/copytest.out';

Attn: You can have "superuser" permission for work with files from sql!

Method #2:

$ psql foodserver -c "COPY company TO stdout" -o /home/peter/copytest.out

This method don't need "superuser" permission...
