The empty-pillar case produced a telegraf.conf with `user= password=`
which libpq misparses ("password=" gets consumed as the user value),
yielding `password authentication failed for user "password="` on
every manager without a prior fan-out (fresh install, not the salt-key
path the reactor handles).
Two fixes:
- salt/postgres/auth.sls: always fan for grains.id in addition to any
postgres_fanout_minion from the reactor, so the manager's own pillar
is populated on every postgres.auth run. The existing `unless` guard
keeps re-runs idempotent.
- salt/telegraf/etc/telegraf.conf: gate the [[outputs.postgresql]]
block on PG_USER and PG_PASS being non-empty. If a minion hasn't
received its pillar yet the output block simply isn't rendered — the
next highstate picks up the creds once the fan-out completes, and in
the meantime telegraf keeps running the other outputs instead of
erroring with a malformed connection string.
