[GENERAL] Upgradede -9.6.1 to -9.6.2; postmaster will not start

   I've tried resolving this but do not see what changed.

   1. Shut down postgres:
     pg_ctl stop -D /var/lib/pgsql/9.6/data

   2. Upgraded version (using SlackBuilds.org package as usual).

   3. Tried re-starting postgres:

postgres@salmo:~$ postgres -D /var/lib/pgsql/9.6/data/ &
[1] 17585
postgres@salmo:~$ LOG:  could not open secondary authentication file

CONTEXT:  line 80 of configuration file
"/var/lib/pgsql/9.6/data/pg_hba.conf"
FATAL:  could not load pg_hba.conf
LOG:  database system is shut down

   4. Line 80 in pg_hba.conf:
@remove-line-for-nolocal@local   all    all   @authmethodlocal@

   5. Tried commenting out that line to match backup, but that also did not
allow postgres to start.

   6. All files are owned by postgres.users.

   Please teach me how to fix this.

TIA,
