That this looks like a merge of the sample file:

https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/backend/libpq/pg_hba.conf.sample;h=6b1778a72136edf52cea56f2ab088b9449df9a48;hb=HEAD

with your additions.

Seems you have not restarted Postgres since the last time you had a
valid pg_hba.conf file. The above is not one. Remove the @***@ strings
and you should be good.
