Setting Table Flag and Inherited Tables

Inherits from
This option specifies a list of tables from which the new table automatically inherits all columns. Use of inheritance creates a persistent relationship between the new child table and its parent table(s). Schema modifications to the parent(s) normally propagate to children as well, and by default the data of the child table is included in scans of the parent(s).

To set the new table to be inherited from one or several existing tables, just simply click to open the editor(s) for editing.

Has Oids
Check this option if you want to specify whether rows of the new table should have OIDs (object identifiers) assigned to them.

Fill Factor
The fillfactor for a table is a percentage between 10 and 100. 100 (complete packing) is the default. When a smaller fillfactor is specified, INSERT operations pack table pages only to the indicated percentage; the remaining space on each page is reserved for updating rows on that page. This gives UPDATE a chance to place the updated copy of a row on the same page as the original, which is more efficient than placing it on a different page. For a table whose entries are never updated, complete packing is the best choice, but in heavily updated tables smaller fillfactors are appropriate.

Note: Support from PostgreSQL 8.2 or later.
