The following bug has been logged on the website:
Bug reference: 16253
Logged by: Regina Obe
Email address: r(at)pcorp(dot)us
PostgreSQL version: 12.1
Operating system: Not relevant
Description:
On the PostgreSQL 12 page of the auth-methods -
https://www.postgresql.org/docs/12/auth-methods.html , it doesn't list a
index of pages to the different auth methods.
I assume this is unintentional since even the development version of the
docs offers links and brief title for each method.
