This commit adds support for database extensions via
salt.states.postgres_extension
When configuring database pillar data all you need to do is add (optional)
extension list with the extensions that you want the state to apply to specific
database. Example:
db1:
owner: 'localUser'
user: 'localUser'
template: 'template0'
lc_ctype: 'C.UTF-8'
lc_collate: 'C.UTF-8'
extensions:
- uuid-ossp
This will make sure `uuid-ossp` extension is enabled on `db1` database.
Updated pillar.example to include (optional) extensions
