Pigsty v0.5.0

Outline

• The official docs site (http://pigsty.cc/) is live.
• Database templating becomes fully declarative: define users, roles, databases, ACLs, extensions, and schemas in config.
• The default access model is refined and HBA management now comes straight from Pigsty instead of Patroni.
• Grafana provisioning switched from shoving a sqlite file to JSON provisioning via API.
• Added the pg-cluster-replication dashboard to the open bundle.
• CentOS 7.8 offline bundle: pkg.tgz.

Multi-tenant headaches go away once everything is described as code. The new templates let you declare users, passwords, role hierarchies, DB defaults, extensions, schemas, and default privileges in YAML so a single config file replaces piles of runbooks. A stripped example:
