|
| <p>Use the <em>Database</em> dialog to define or modify a database. To create a database,
|
| you must be a database superuser or have the CREATE privilege.</p>
|
| <p>The <em>Database</em> dialog organizes the development of a database through the
|
| following dialog tabs: <em>General</em>, <em>Definition</em>, <em>Security</em>, and <em>Parameters</em>.
|
| The <em>SQL</em> tab displays the SQL code generated by dialog selections.</p>
|
| <img alt="Database dialog general tab" class="align-center" src="_images/database_general.png" />
|
| <p>Use the fields in the <em>General</em> tab to identify the database:</p>
|
| <ul class="simple">
|
| <li><p>Use the <em>Database</em> field to add a descriptive name for the database. The name
|
| will be displayed in the <em>pgAdmin</em> tree control.</p></li>
|
| <li><p>Use the <em>OID</em> field to specify the object identifier to be used for the new
|
| database. Users can specify the value greater than 16383. This option is available
|
| from v15 and above.</p></li>
|
| <li><p>Select the owner of the database from the drop-down listbox in the <em>Owner</em>
|
| field.</p></li>
|
| <li><p>Store notes about the database in the <em>Comment</em> field.</p></li>
|
| </ul>
|
| <p>Click the <em>Definition</em> tab to continue.</p>
|
| <img alt="Database dialog definition tab" class="align-center" src="_images/database_definition.png" />
|
| <p>Use the <em>Definition</em> tab to set properties for the database:</p>
|
| <ul class="simple">
|
| <li><p>Select a character set from the drop-down listbox in the <em>Encoding</em> field.
|
| The default is <em>UTF8</em>.</p></li>
|
| <li><p>Select a template from the drop-down listbox in the <em>Template</em> field. If you
|
| do not specify a template, the database will use template1.</p></li>
|
| <li><p>Select a tablespace from the drop-down listbox in the <em>Tablespace</em> field. The
|
| selected tablespace will be the default tablespace used to contain database
|
| objects.</p></li>
|
| <li><p>Select the strategy from the drop-down listbox in the <em>Strategy</em> field while
|
| creating a new database. This option is available from v15 and above.</p></li>
|
| <li><p>Select the locale provider from the drop-down listbox in the <em>Locale Provider</em>
|
| field to set the default collation for this database. Possible values are: icu, libc.
|
| This option is available from v15 and above.</p></li>
|
| <li><p>Select the collation order from the drop-down listbox in the <em>Collation</em> field.</p></li>
|
| <li><p>Select the character classification from the drop-down listbox in the
|
| <em>Character Type</em> field. This affects the categorization of characters, e.g.
|
| lower, upper and digit. The default, or a blank field, uses the character
|
| classification of the template database.</p></li>
|
| <li><p>Select the icu locale from the drop-down listbox in the <em>ICU Locale</em> to
|
| specifies the ICU locale ID if the ICU locale provider is used.
|
| This option is available from v15 and above.</p></li>
|
| <li><p>Specify the icu rules in the <em>ICU Rules</em> field as additional collation
|
| rules to customize the behavior of the default collation of this database.
|
| This option is available from v16 and above.</p></li>
|
| <li><p>Specify a connection limit in the <em>Connection Limit</em> field to configure the
|
| maximum number of connection requests. The default value (<em>-1</em>) allows
|
| unlimited connections to the database.</p></li>
|
| <li><p>If the <em>templates?</em> is set to true, then database will be a template database.</p></li>
|
| </ul>
|
| <p>Click the <em>Security</em> tab to continue.</p>
|
| <img alt="Database dialog security tab" class="align-center" src="_images/database_security.png" />
|
| <p>Use the <em>Security</em> tab to assign privileges and define security labels.</p>
|
| <p>Use the <em>Privileges</em> panel to assign privileges to a role. Click the <em>Add</em> icon
|
| (+) to set privileges for database objects:</p>
|
| <ul class="simple">
|
| <li><p>Select the name of the role from the drop-down listbox in the <em>Grantee</em> field.</p></li>
|
| <li><p>Click inside the <em>Privileges</em> field. Check the boxes to the left of one or
|
| more privileges to grant the selected privilege to the specified user.</p></li>
|
| <li><p>The current user, who is the default grantor for granting the privilege, is displayed in the <em>Grantor</em> field.</p></li>
|
| </ul>
|
| <p>Click add to set additional privileges; to discard a privilege, click the trash
|
| icon to the left of the row and confirm deletion in the <em>Delete Row</em> popup.</p>
|
| <p>Use the <em>Security Labels</em> panel to define security labels applied to the
|
| database. Click the <em>Add</em> icon (+) to add each security label selection:</p>
|
| <ul class="simple">
|
| <li><p>Specify a security label provider in the <em>Provider</em> field. The named provider
|
| must be loaded and must consent to the proposed labeling operation.</p></li>
|
| <li><p>Specify a a security label in the <em>Security Label</em> field. The meaning of a
|
| given label is at the discretion of the label provider. PostgreSQL places no
|
| restrictions on whether or how a label provider must interpret security
|
| labels; it merely provides a mechanism for storing them.</p></li>
|
| </ul>
|
| <p>To discard a security label, click the trash icon to the left of the row and
|
| confirm deletion in the <em>Delete Row</em> popup.</p>
|
| <p>Click the <em>Parameters</em> tab to continue.</p>
|
| <img alt="Database dialog parameters tab" class="align-center" src="_images/database_parameters.png" />
|
| <p>Use the <em>Parameters</em> tab to set parameters for the database. Click the <em>Add</em>
|
| icon (+) to add each parameter:</p>
|
| <ul class="simple">
|
| <li><p>Use the drop-down listbox in the <em>Name</em> field to select a parameter.</p></li>
|
| <li><p>Use the <em>Value</em> field to set a value for the parameter.</p></li>
|
| <li><p>Use the drop-down listbox next to <em>Role</em> to select a role to which the
|
| parameter setting specified will apply.</p></li>
|
| </ul>
|
| <p>Follow these steps to add additional parameter value definitions; to discard a
|
| parameter, click the trash icon to the left of the row and confirm deletion in
|
| the <em>Delete Row</em> popup.</p>
|
| <p>Click the <em>Advanced</em> tab to continue.</p>
|
| <img alt="Database dialog advanced tab" class="align-center" src="_images/database_advanced.png" />
|
| <p>Use the <em>Advanced</em> tab to set advanced parameters for the database.</p>
|
| <ul class="simple">
|
| <li><p>Use <em>Schema restriction</em> field to provide a SQL restriction that will be used
|
| against the pg_namespace table to limit the schemas that you see.
|
| For example, you might enter: <em>public</em> so that only <em>public</em> are shown in
|
| the pgAdmin browser.Separate entries with a comma or tab as you type.</p></li>
|
| </ul>
|
| <p>Click the <em>SQL</em> tab to continue.</p>
|
| <p>Your entries in the <em>Database</em> dialog generate a SQL command (see an example
|
| below). Use the <em>SQL</em> tab for review; revisit or switch tabs to make any changes
|
| to the SQL command.</p>
|
| <section id="example">
|
| <h2>Example<a class="headerlink" href="#example" title="Link to this heading">¶</a></h2>
|
| <p>The following is an example of the sql command generated by user selections in
|
| the <em>Database</em> dialog:</p>
|
| <img alt="Database dialog sql tab" class="align-center" src="_images/database_sql.png" />
|
| <p>The example creates a database named <em>hr</em> that is owned by <em>postgres</em>. It
|
| allows unlimited connections, and is available to all authenticated users.</p>
|
| <ul class="simple">
|
| <li><p>Click the <em>Info</em> button (i) to access online help.</p></li>
|
| <li><p>Click the <em>Save</em> button to save work.</p></li>
|
| <li><p>Click the <em>Close</em> button to exit without saving work.</p></li>
|
| <li><p>Click the <em>Reset</em> button to restore configuration parameters.</p></li>
