I reviewed this patch. It works as expected but I have few remarks :

  * There is a warning during compilation :

gram.y: In function ‘base_yyparse’:
gram.y:2090:6: warning: ISO C90 forbids mixed declarations and code
[-Wdeclaration-after-statement]
      AlterTableCmd *n = makeNode(AlterTableCmd);
      ^~~~~~~~~~~~~

If I understand we should declare AlterTableCmd *n [...] before "if"?

  * I propose to add "Stats target" information in psql verbose output command
\d+ (patch attached with test)

\d+ tmp_idx
                     Index "public.tmp_idx"
 Column |       Type       | Definition | Storage | Stats target
--------+------------------+------------+---------+--------------
 a      | integer          | a          | plain   |

 b      | cstring          | b          | plain   |
btree, for table "public.tmp"


  * psql completion is missing (added to previous patch)
