Done.


I have gotten the error that AlterUserMappingStmt doesn't have if_not_exists (in Russian):

gram.y: В функции «base_yyparse»:
gram.y:4918:7: ошибка: «AlterUserMappingStmt {aka struct AlterUserMappingStmt}» 
не содержит элемента с именем «if_not_exists»
      n->if_not_exists = false;
       ^~

After applying the CREATE USER patch in gram.y I have:


AlterUserMappingStmt: ALTER USER MAPPING FOR auth_ident SERVER name 
alter_generic_options
                {
                    AlterUserMappingStmt *n = makeNode(AlterUserMappingStmt);
                    n->user = $5;
                    n->servername = $7;
                    n->options = $8;
                    n->if_not_exists = false;
                    $$ = (Node *) n;
                }
                | CREATE USER MAPPING IF_P NOT EXISTS FOR auth_ident SERVER 
name create_generic_options
                {
                    CreateUserMappingStmt *n = makeNode(CreateUserMappingStmt);
                    n->user = $8;
                    n->servername = $10;
                    n->options = $11;
                    n->if_not_exists = true;
                    $$ = (Node *) n;
                }
        ;

Here ALTER USER MAPPING and CREATE USER MAPPING commands were mixed.
