Title: CREATE TABLE Syntax Details: Constraints, LIKE Options, and Referential Actions
Summary
This section continues the syntax definition for the CREATE TABLE command, focusing on the specifics of table constraints like FOREIGN KEY (including PERIOD), and EXCLUDE, as well as LIKE options for copying table definitions. It provides details on partition bound specifications, index parameters, exclude elements within EXCLUDE constraints, and referential actions (NO ACTION, RESTRICT, CASCADE, SET NULL, SET DEFAULT) in FOREIGN KEY constraints. Finally, it gives a brief description of the CREATE TABLE command and where the table will be created (schema).
