`setup_repo` | Boolean | Define if you want to add the PostgreSQL repo | true | no
`hba_file` | String | Path of pg_hba.conf file | `<default_os_path>/pg_hba.conf'` | no
`ident_file` | String | Path of pg_ident.conf file | `<default_os_path>/pg_ident.conf` | no

end
```
#### Known issues
On some platforms (e.g. Ubuntu 18.04), your `initdb_locale` should be set to the
same as the template database [GH-555](https://github.com/sous-chefs/postgresql/issues/555).

postgresql_server_conf 'My PostgreSQL Config' do
version '9.5'
data_directory '/data/postgresql/9.5/main'
notifies :reload, 'service[postgresql]'
end
```
### postgresql_extension
This resource manages PostgreSQL extensions for a given database.
#### Actions

package 'postgresql-contrib-9.6'
# Install adminpack extension
postgresql_extension 'postgres adminpack' do
database 'postgres'
extension 'adminpack'
end
```
### postgresql_access
This resource uses the accumulator pattern to build up the `pg_hba.conf` file via chef resources instead of piling on a mountain of chef attributes to make this cookbook more reusable. It directly mirrors the configuration options of the postgres hba file in the resource and by default notifies the server with a reload to avoid a full restart, causing a potential outage of service. To revoke access, simply remove the resource and the access change won't be computed into the final `pg_hba.conf`
#### Actions
- `grant` - (default) Creates an access line inside of `pg_hba.conf`
#### Properties
Name | Types | Description | Default | Required?
--------------- | ------ | ----------------------------------------------------------------------------------------- | ----------------- | ---------
`name` | String | Name of the access resource, this is left as a comment inside the `pg_hba` config | Resource name | yes
`source` | String | The cookbook template filename if you want to use your own custom template | 'pg_hba.conf.erb' | yes
`cookbook` | String | The cookbook to look in for the template source | 'postgresql' | yes
`comment` | String | A comment to leave above the entry in `pg_hba` | nil | no
`access_type` | String | The type of access, e.g. local or host | 'local' | yes
`access_db` | String | The database to access. Can use 'all' for all databases | 'all' | yes
`access_user` | String | The user accessing the database. Can use 'all' for any user | 'all' | yes
`access_addr` | String | The address(es) allowed access. Can be nil if method ident is used since it is local then | nil | no
`access_method` | String | Authentication method to use | 'ident' | yes
#### Examples
To grant access to the PostgreSQL user with ident authentication:
```ruby
postgresql_access 'local_postgres_superuser' do
comment 'Local postgres superuser access'
access_type 'local'
access_db 'all'
access_user 'postgres'
access_addr nil
access_method 'ident'
end
```
This generates the following line in the `pg_hba.conf`:
```config
# Local postgres superuser access
local all postgres ident
```
**Note**: The template by default generates a local access for Unix domain sockets only to support running the SQL execute resources. In Postgres version 9.1 and higher, the method is 'peer' instead of 'ident' which is identical. It looks like this:
```config
# "local" is for Unix domain socket connections only
local all all peer
```
### postgresql_ident
This resource generate `pg_ident.conf` configuration file to manage user mapping between system and PostgreSQL users.
#### Actions
- `create` - (default) Creates an mapping line inside of `pg_ident.conf`
#### Properties
Name | Types | Description | Default | Required?
-------------- | ----------- | -------------------------------------------------------------------------- | ------------------- | ---------
`mapname` | String | Name of the user mapping | Resource name | yes
`source` | String | The cookbook template filename if you want to use your own custom template | 'pg_ident.conf.erb' | no
`cookbook` | String | The cookbook to look in for the template source | 'postgresql' | no
`comment` | String, nil | A comment to leave above the entry in `pg_ident` | nil | no
`system_user` | String | System user or regexp used for the mapping | None | yes
`pg_user` | String | Pg user or regexp used for the mapping | None | yes
#### Examples
Creates a `mymapping` mapping that map `john` system user to `user1` PostgreSQL user:
```ruby
postgresql_ident 'Map john to user1' do
comment 'John Mapping'
mapname 'mymapping'
system_user 'john'
pg_user 'user1'
end
```
This generates the following line in the `pg_ident.conf`:
```config
# MAPNAME SYSTEM-USERNAME PG-USERNAME
# John Mapping
mymapping john user1
```
To grant access to the foo user with password authentication:
```ruby
postgresql_access 'local_foo_user' do
comment 'Foo user access'
access_type 'host'
access_db 'all'
access_user 'foo'
access_addr '127.0.0.1/32'
access_method 'md5'
end
```
This generates the following line in the `pg_hba.conf`:
```config
# Local postgres superuser access
host all foo 127.0.0.1/32 ident
```
### postgresql_database

valid_until '2018-12-31'

```ruby
postgresql_user 'user1' do

## Usage
To install and configure your PostgreSQL instance you need to create your own cookbook and call needed resources with your own parameters.
More examples can be found in `test/cookbooks/test/recipes`
## Example Usage
```ruby
# cookbooks/my_postgresql/recipes/default.rb
postgresql_client_install 'PostgreSQL Client' do
setup_repo false
version '10.6'
end
postgresql_server_install 'PostgreSQL Server' do
version '10.6'
setup_repo false
password 'P0stgresP4ssword'
end
postgresql_server_conf 'PostgreSQL Config' do
notifies :reload, 'service[postgresql]'
end
```
