Well first, if you are going to use trust as your auth method then specifying a password is moot exercise.

  I tried adding an explicit password to ~/.pgpass with md5 as the auth
method, but that didn't work so I went back to trust. That's served well for
19 years. :-)

Second, not sure where you are in the process, but any time you change the
pg_hba.conf file you will need to give Postgres a reload signal to get it
to recognize the changes. Again not sure how you are signalling Postgres
but if you are using pg_ctl
https://www.postgresql.org/docs/9.5/static/app-pg-ctl.html
then something like:

pg_ctl reload  -D path_to_your_datadir

as OS user postgres.

  Good to know. I use pg_ctl stop and start with the path on both command
lines.

Third, .pgpass should hold information that already exists in the database
system tables. It is not a mechanism for entering that information into
the database. So yes, you will need to use ALTER ROLE to create the
password inside Postgres.

  OK. I'll try that for the learning experience.

  So much to learn and so little time ...

Thanks,

Rich
