Add support for LIKE in CREATE FOREIGN TABLE
LIKE enables the creation of foreign tables based on the column
definitions, constraints and objects of the defined source relation(s).
This feature mirrors the behavior of CREATE TABLE LIKE, but ignores
the INCLUDING sub-options that do not make sense for foreign tables:
INDEXES, COMPRESSION, IDENTITY and STORAGE. The supported sub-options
are COMMENTS, CONSTRAINTS, DEFAULTS, GENERATED and STATISTICS, mapping
with the clauses already supported by the command.
Note that the restriction with LIKE in CREATE FOREIGN TABLE was added in
a0c6dfeecfcc.
