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,

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...

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

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...
