Create a schema
Click the data source in which you want to create a schema.
In the Name field, specify a name of the schema.
Select the default schema
You can select the default schema or database by using the list in the right-hand part of the toolbar. If you do so, you'll be able to omit the name of that schema or database in your statements.
Click the <session> list and select the schema that you need.
Show and hide schemas
You can select what schemas you want to show in the database tree view.
In the Database tool window ( ), right-click a data source and navigate to . Select or clear checkboxes of schemas that you want to enable or disable. Press Enter.

Set the schema search path for PostgreSQL and Redshift
search_path environment variable in PostgreSQL specifies the order in which schemas are searched. For example, you set the value of
z,a,public, PostgreSQL will look for a value in the
z schema. If nothing was not found in the
z schema, PostgreSQL looks for the value in the
In PostgreSQL and Amazon Redshift, the default search path (the path that is set in a database) is used unless you specify a different search path.
Click the <session> list, navigate to the list of database schemas (use the arrow icon or press the right arrow key).
Select the schema that you want to add to a search path.
To form a search path, you can use the following actions:
Press Space to add a highlighted schema to the search path and to remove a schema from the search path.
Press Alt+Up and Alt+Down to reorder the schemas within the search path.
To apply the changes, press OK.
Force refresh schema information
The Force Refresh action clears the data source information from cache and loads it again from scratch.
In the Database tool window ( ), right-click a data source and select .
Show objects from system catalogs in coding assistance
A system catalog is the place where a relational database management system (DBMS) stores information about tables and columns, built-in functions, and other schema objects. These objects are used in coding assistance (for example, code completion).
System schemas have the lightning icon in the schema selection dialog. If you do not select these schemas, IntelliJ IDEA will not introspect them and will not show them in the Database tool window. Though information about schema objects will be used in coding assistance. It is possible because IntelliJ IDEA uses internal data about schema objects that was introspected earlier.
Examples of system catalogs in different DBMS:
PostgreSQL: pg_catalog, information_schema
Microsoft SQL Server: INFORMATION_SCHEMA
Oracle: SYS, SYSTEM
IBM Db2: SYSCAT, SYSFUN, SYSIBM, SYSIBMADM, SYSPROC, SYSPUBLIC, SYSSTAT, SYSTOOLS
