Incorrect syntax in latest postgres docs

[ayleph]

A recent commit [1] introduced an error in the postgresql configuration. The docs say:

# su -u postgres

but this doesn't work as -u is not a valid switch to su (at least not my system and not on the system of ramsesHD who pointed this out to me on IRC). It seems the correct syntax should be

# su - postgres
