Thread: Permission problem with COPY FROM

Hi,

    I've faced that problem too, then I use '\copy' instread
of 'copy' because 'copy' command will asked for super user previlege.
example
^^^^^^ -> \copy '/your location/your filename' to tablename;

Cheers,

It's not that; the error message Stephane quotes is after the
Postgres superuser-privilege check:

>> "ERROR: COPY command, running in backend with effective uid 501

This is a result of the Unix kernel denying read access to the file.
It's got to be a matter of not having read rights on the file or not
having lookup (x) rights on one of the directories above it.

psql's \copy is often a better choice than the regular SQL COPY command,
though.  It reads or writes the file with the privileges of the user
running psql, rather than those of the Postgres server, which is usually
a Good Thing.  Also, if you are contacting a server on a different
machine, \copy works with files in the local filesystem, not the
server's filesystem.

The problem does not seem to be with the permissions --- it has been
on the list a number of times already. Try using psql's \copy instead.
