Someone submitted a comment to the docs (which I'll shortly delete)
which points out a typo on the CREATE USER MAPPING page in the docs.
A very brief patch is attached.
They also added: "Also concerning this paragraph: a little more detail
on how exactly the two sources of encapsuled information are combined
would be helpful."
Thanks
