I moved the postgres data directory to a separate partition and it works great. The directory is owned by postgres user and postgres group.

d-wx------ 11 postgres postgres 4.0K 2010-06-11 08:28 data/

I added myself to the group

> sudo addgroup me postgres

> groups me

me : me adm dialout cdrom plugdev lpadmin admin sambashare postgres

And gave the group read and execute permissions to everything in the directory.

sudo chmod -R g+rx ./data

d-wxr-x--- 11 postgres postgres 4.0K 2010-06-11 08:28 data/

But I still can not CD or LS the directory.

> ls data

ls: cannot open directory data: Permission denied

What beginner mistake am I making?
