Should REINDEX be listed under DDL?

Hi all,

On a recent thread about adding support for event triggers with
REINDEX, a change has been proposed to make REINDEX queries reflect in
the logs under the DDL category:
https://www.postgresql.org/message-id/ZW0ltJXJ2Aigvizl%40paquier.xyz

REINDEX being classified as LOGSTMT_ALL comes from 893632be4e17 back
in 2006, and the code does not know what to do about it.  Doing the
change would be as simple as that:
        case T_ReindexStmt:
-           lev = LOGSTMT_ALL;  /* should this be DDL? */
+           lev = LOGSTMT_DDL;

REINDEX is philosophically a maintenance command and a Postgres
extension not in the SQL standard, so it does not really qualify as a
DDL because it does not do in object definitions, so we could just
delete this comment.  Or could it be more useful to consider that as a
special case and report it as a DDL, impacting log_statements?

Any thoughts?
