![]() The user creating the database is the only DBA and the only one who can drop the database, other than the postgres superuser. Note: createdb internally runs CREATE DATABASE from psql while connected to the template1 database. To create a database with parameters, add the keyword WITH after the CREATE DATABASE statement and then list the parameters you want. In SQL Server, this statement creates a new database and the files used and their filegroups. Otherwise, only superusers or the database owner can clone the database. It can also be used to create a database snapshot, or attach database files to create a database from the detached files of another database. For more information about the syntax conventions, see Transact-SQL Syntax Conventions. Setting IS_TEMPLATE to TRUEallows any user with the CREATEDBprivilege to clone the database. Startups including big companies such as Apple, Cisco, Redhat and more use Postgres to drive their business. Set the IS_TEMPLATE parameter to TRUE or FALSE. The default value is -1, which means unlimited connections. The CONNECTION LIMIT parameter lets you to set the maximum simultaneous connections to a PostgreSQL database. Specifying the value as FALSE prevents you from connecting to the database. The ALLOW_CONNECTIONS parameter can be TRUE or FALSE. Omitting the TABLESPACE parameter takes the tablespace name of the template database. Use the TABLESPACE parameter to specify the tablespace name for the new database. Omitting the LC_CTYPE parameter takes the default settings from the template database. Character classification includes lower, upper case, and digits. The LC_CTYPE parameter specifies the character classification used in the new database. Omitting the LC_COLLATE parameter takes the settings from the template database. The effect is visible when using a locale that contains special characters. This parameter controls the string sort order in the ORDER BY clause. The LC_COLLATE parameter specifies the collation order of the new database. The ENCODING parameter determines the character set encoding in the new database. Omitting the TEMPLATE parameter sets template1 as the default template database. Make sure that the keyboard focus is on the table view in Postico and paste your data. The TEMPLATE parameter allows you to specify the template database from which to create the new database. You should now see all your new data highlighted in yellow. Check that everything was pasted correctly, then click save to write changes to the database. ![]() Exporting CSV files Postico can export tables and query results as 'Comma Separated Values' (CSV) files. Omitting the OWNER parameter means that the database owner is the role used to execute the CREATE DATABASE statement. Using the superuser credentials, you can create databases, users, and whatever else you need for your apps. The OWNER parameter assigns the database owner role.
