Mike Reeves 7b9ab2d9d1 postsalt: enable PG-canonical pillar mode by default during so-setup
Drops a local pillar override (postgres.so_pillar.enabled = True) right
after secrets_pillar so the install-time highstate brings up
schema_pillar, ext_pillar_postgres, and the pg_notify_pillar engine
without operator intervention. Without this the whole PG-canonical
stack stays gated off on the default-False flag and the install lands
in legacy disk-pillar mode — which defeats the point of being on the
postsalt branch at all.

The new enable_so_pillar_postgres() function in so-functions is
idempotent (overwrites adv_postgres.sls with a fixed body) and the
generated file is mode 0644 socore:socore so it merges into pillar
under the existing local-pillar directory ownership convention.

Rollback path: edit /opt/so/saltstack/local/pillar/postgres/adv_postgres.sls
to set enabled: False, or delete the file. The schema and engine
config states will tear themselves down on the next highstate via
their existing else-branch absent states.
