commit    c4325cefba512772efc108baf8ef7182c3833716
Author:   Peter Eisentraut <peter@eisentraut.org>
Date:     Thu Jun 11 06:21:24 2020 +0000
First released in: 14.0

    Fold AlterForeignTableStmt into AlterTableStmt
    
    All other relation types are handled by AlterTableStmt, so it's
    unnecessary to make a different statement for foreign tables.
