   that this index depends on (for example, edbspl). If set, dropping the extension 
   will automatically drop the index as well.
+* Move the switch next to *Only Table?* to the *Yes* position to create the index
+  only on the parent table without recursing to its partitions. This button will be
+  enabled for partition tables only. The default is *No*.
+* Move the switch next to *Unique?* to the *Yes* position to check for duplicate values
+  in the table when the index is created and when data is added. The default is *No*.
+* Move the switch next to *NULLs not distinct?* to the *Yes* position to treat null values as not distinct. 
+  The default is *No*. This option is available only on PostgreSQL 15 and above.
+* Move the *Clustered?* switch to the *Yes* position to instruct the server to
+  cluster the table.
+* Move the *Concurrent build?* switch to the *Yes* position to build the index
+  without taking any locks that prevent concurrent inserts, updates, or deletes
+  on the table.
+* Use the *Constraint* field to provide a constraint expression; a constraint
+  expression limits the entries in the index to those rows that satisfy the
+  constraint.
