# postgresql\_database

The ``postgresql_database`` resource creates and manages [database
objects](https://www.postgresql.org/docs/current/static/managing-databases.html)
within a PostgreSQL server instance.


## Usage

```
resource "postgresql_database" "my_db" {
   name = "my_db"
   owner = "my_role"
   template = "template0"
   collation = "C"
   connection_limit = -1
   allow_connections = true
}

```

## Argument Reference

* `name` - (Required) The name of the database. Must be unique on the PostgreSQL
  server instance where it is configured.

* `owner` - (Optional) The role name of the user who will own the database, or
  `DEFAULT` to use the default (namely, the user executing the command). To
  create a database owned by another role or to change the owner of an existing
  database, you must be a direct or indirect member of the specified role, or
  the username in the provider is a superuser.

* `tablespace_name` - (Optional) The name of the tablespace that will be
  associated with the database, or `DEFAULT` to use the template database's
  tablespace.  This tablespace will be the default tablespace used for objects
  created in this database.

* `connection_limit` - (Optional) How many concurrent connections can be
  established to this database. `-1` (the default) means no limit.

* `allow_connections` - (Optional) If `false` then no one can connect to this
  database. The default is `true`, allowing connections (except as restricted by
  other mechanisms, such as `GRANT` or `REVOKE CONNECT`).

* `is_template` - (Optional) If `true`, then this database can be cloned by any
  user with `CREATEDB` privileges; if `false` (the default), then only
  superusers or the owner of the database can clone it.

* `template` - (Optional) The name of the template database from which to create
  the database, or `DEFAULT` to use the default template (`template0`).  NOTE:
  the default in Terraform is `template0`, not `template1`.  Changing this value
  will force the creation of a new resource as this value can only be changed
  when a database is created.

* `encoding` - (Optional) Character set encoding to use in the database.
  Specify a string constant (e.g. `UTF8` or `SQL_ASCII`), or an integer encoding
  number.  If unset or set to an empty string the default encoding is set to
  `UTF8`.  If set to `DEFAULT` Terraform will use the same encoding as the
  template database.  Changing this value will force the creation of a new
  resource as this value can only be changed when a database is created.

* `lc_collate` - (Optional) Collation order (`LC_COLLATE`) to use in the
  database.  This affects the sort order applied to strings, e.g. in queries
  with `ORDER BY`, as well as the order used in indexes on text columns. If
  unset or set to an empty string the default collation is set to `C`.  If set
  to `DEFAULT` Terraform will use the same collation order as the specified
  `template` database.  Changing this value will force the creation of a new
  resource as this value can only be changed when a database is created.

* `lc_ctype` - (Optional) Character classification (`LC_CTYPE`) to use in the
  database. This affects the categorization of characters, e.g. lower, upper and
  digit. If unset or set to an empty string the default character classification
  is set to `C`.  If set to `DEFAULT` Terraform will use the character
  classification of the specified `template` database.  Changing this value will
  force the creation of a new resource as this value can only be changed when a
  database is created.

## Import Example

`postgresql_database` supports importing resources.  Supposing the following
Terraform:

```
provider "postgresql" {
  alias = "admindb"
}

resource "postgresql_database" "db1" {
  provider = "postgresql.admindb"

  name = "testdb1"
}
```

It is possible to import a `postgresql_database` resource with the following
command:

```
$ terraform import postgresql_database.db1 testdb1
```

Where `testdb1` is the name of the database to import and
`postgresql_database.db1` is the name of the resource whose state will be
populated as a result of the command.
