Some parameters need to be specified explicitly when deploying on Ubuntu, please refer to [`ubuntu.yml`](https://github.com/Vonng/pigsty/blob/master/files/pigsty/ubuntu.yml)

- `repo_upstream`: Adjust according to ubuntu / debian repo.
- `repo_packages`: Adjust according to ubuntu / debian naming convention
- `node_repo_local_urls`: use the default value: `['deb [trusted=yes] http://${admin_ip}/pigsty ./']`
- `node_default_packages` ：
  - `zlib` -> `zlib1g`, `readline` -> `libreadline-dev`
  - `vim-minimal` -> `vim-tiny`, `bind-utils` -> `dnsutils`, `perf` -> `linux-tools-generic`,
  - new packages `acl` to ensure ansible tmp file privileges are set correctly
- `infra_packages`: replace all `_` with `-` in names, and replace `postgresql16` with `postgresql-client-16`

- `pg_extensions`: different naming convention, no `passwordcheck_cracklib` on ubuntu.
- `pg_dbsu_uid`: You have to manually specify `pg_dbsu_uid` on ubuntu, because PGDG deb package does not specify pg dbsu uid.

----------------

## v1.4.0

**Architecture**

* Decouple system into 4 major categories:  `INFRA`, `NODES`, `PGSQL`, `REDIS`, which makes pigsty far more clear and more extensible.
* Single Node Deployment = `INFRA` + `NODES` + `PGSQL`
* Deploy pgsql clusters = `NODES` + `PGSQL`
* Deploy redis clusters = `NODES` + `REDIS`
* Deploy other databases = `NODES` + xxx (e.g `MONGO`, `KAFKA`, ... TBD)


**Accessibility**

* CDN for mainland China.
* Get the latest source with `bash -c "$(curl -fsSL http://get.pigsty.cc/latest)"`
* Download & Extract packages with new `download` script.

* Logging enabled by default
  * now `loki` and `promtail` are enabled by default. with prebuilt [loki-rpm](https://github.com/Vonng/loki-rpm)
* Models & Labels
  * A hidden `ds` prometheus datasource variable is added for all dashboards, so you can easily switch different datasource simply by select a new one rather than modifying Grafana Datasources & Dashboards
  * An `ip` label is added for all metrics, and will be used as join key between database metrics & nodes metrics
* INFRA Monitoring
  * Home dashboard for infra: INFRA Overview
  * Add logging Dashboards : Logs Instance
  * PGLOG Analysis & PGLOG Session now treated as an example Pigsty APP.
* NODES Monitoring Application
  * If you don't care database at all, Pigsty now can be used as host monitoring software alone!
  * Consist of 4 core dashboards: Nodes Overview & Nodes Cluster & Nodes Instance & Nodes Alert
  * Introduce new identity variables for nodes: `node_cluster` and `nodename`
  * Variable `pg_hostname` now means set hostname same as postgres instance name to keep backward-compatible
  * Variable `nodename_overwrite` control whether overwrite node's hostname with nodename
  * Variable `nodename_exchange` will write nodename to each other's `/etc/hosts`
  * All nodes metrics reference are overhauled, join by `ip`
  * Nodes monitoring targets are managed alone under `/etc/prometheus/targets/nodes`
* PGSQL Monitoring Enhancement
  * Complete new PGSQL Cluster which simplify and focus on important stuff among cluster.
  * New Dashboard PGSQL Databases which is cluster level object monitoring. Such as tables & queries among the entire cluster rather than single instance.
  * PGSQL Alert dashboard now only focus on pgsql alerts.
  * PGSQL Shard are added to PGSQL
* Redis Monitoring Enhancement
  * Add nodes monitoring for all redis dashboards.


**MatrixDB Support**

* MatrixDB (Greenplum 7) can be deployed via `pigsty-matrix.yml` playbook
* MatrixDB Monitor Dashboards : PGSQL MatrixDB
* Example configuration added: `pigsty-mxdb.yml`


**Provisioning Enhancement**

Now pigsty work flow works as this:

```bash
 infra.yml ---> install pigsty on single meta node
      |          then add more nodes under pigsty's management
      |
 nodes.yml ---> prepare nodes for pigsty (node setup, dcs, node_exporter, promtail)
      |          then choose one playbook to deploy database clusters on those nodes
      |
      ^--> pgsql.yml   install postgres on prepared nodes
      ^--> redis.yml   install redis on prepared nodes

infra-demo.yml = 
           infra.yml -l meta     +
           nodes.yml -l pg-test  +
           pgsql.yml -l pg-test +
           infra-loki.yml + infra-jupyter.yml + infra-pgweb.yml
 
```

* `nodes.yml` to setup & prepare nodes for pigsty
  *  setup node, node_exporter, consul agent on nodes
  * `node-remove.yml` are used for node de-register
* `pgsql.yml` now only works on prepared nodes
  * `pgsql-remove` now  only responsible for postgres itself. (dcs and node monitor are taken by `node.yml`)

**How to upgrade from v1.1.1**

There's no API change in 1.2.0 You can still use old `pigsty.yml` configuration files (PG13).

For the infrastructure part. Re-execution of `repo` will do most of the parts

As for the database. You can still use the existing PG13 instances. In-place upgrade is quite
tricky especially when involving extensions such as PostGIS & Timescale. I would highly recommend
performing a database migration with logical replication.

The new playbook `pgsql-migration.yml` will make this a lot easier. It will create a series of
scripts which will help you to migrate your cluster with near-zero downtime.

```

**Service**

`pg_services` and `pg_services_extra` Defines the services in cluster:

A service has some mandatory fields:

* `name`: service's name
* `src_port`: which port to listen and expose service?
* `selector`: which instances belonging to this service?

```yaml
  # default service will route {ip|name}:5436 to primary postgres (5436->5432 primary)
  - name: default           # service's actual name is {{ pg_cluster }}-{{ service.name }}
    src_ip: "*"             # service bind ip address, * for all, vip for cluster virtual ip address
    src_port: 5436          # bind port, mandatory
    dst_port: postgres      # target port: postgres|pgbouncer|port_number , pgbouncer(6432) by default
    check_method: http      # health check method: only http is available for now
    check_port: patroni     # health check port:  patroni|pg_exporter|port_number , patroni by default
    check_url: /primary     # health check url path, / as default
    check_code: 200         # health check http code, 200 as default
    selector: "[]"          # instance selector
    haproxy:                # haproxy specific fields
      maxconn: 3000         # default front-end connection
      balance: roundrobin   # load balance algorithm (roundrobin by default)
      default_server_options: 'inter 3s fastinter 1s downinter 5s rise 3 fall 3 on-marked-down shutdown-sessions slowstart 30s maxconn 3000 maxqueue 128 weight 100'
```

**Database**

Add additional locale support: `lc_ctype` and `lc_collate`.

It's mainly because of `pg_trgm` 's weird behavior on i18n characters.

```yaml
pg_databases:
  - name: meta                      # name is the only required field for a database
    # owner: postgres                 # optional, database owner

    allowconn: true                 # optional, true by default, false disable connect at all
    revokeconn: false               # optional, false by default, true revoke connect from public # (only default user and owner have connect privilege on database)
    # tablespace: pg_default          # optional, 'pg_default' is the default tablespace
    connlimit: -1                   # optional, connection limit, -1 or none disable limit (default)
    extensions:                     # optional, extension name and where to create
      - {name: postgis, schema: public}
    parameters:                     # optional, extra parameters with ALTER DATABASE
      enable_partitionwise_join: true
    pgbouncer: true                 # optional, add this database to pgbouncer list? true by default

      search_path: public
    comment: test user
```

**Changes**

* `username` field rename to `name`
* `groups` field rename to `roles`
* `options` now split into separated configration entries:
  `login`, `superuser`, `createdb`, `createrole`, `inherit`, `replication`,`bypassrls`,`connlimit`
* `expire_at` and `expire_in` options
* `pgbouncer` option for user is now `false` by default

**Apply Changes**

You can create new users on running postgres clusters with `pgsql-createuser.yml` playbook.
1. Define your new users in config files (`pg_users`)
2. Pass new user.name with option `pg_user` to playbook.

```bash
./pgsql-createuser.yml -e pg_user=<your_new_user_name>
```
