This is rendered as

which IMO isn't too helpful. Maybe a <link> would read better than an
<xref>?
Also, this function's placement in the docs (with the System Catalog
Information Functions) seems wrong to me. I think it should go up above
in the Session Information Functions, with current_user et al.

If we're palloc'ing anyway, can this be replaced with a single psprintf()?

It makes me a little nervous to call hba_authname(auth_method) without
checking to see that auth_method is actually valid (which is only true
if authn_id is not NULL).
We could pass the bare auth_method index, or update the documentation
for auth_method to state that it's guaranteed to be zero if authn_id is
NULL (and then enforce that).

Should this be moved to use TEXTOID instead?
