1、Debezium目前魔仍只能同步到dml操作，如果做细粒度的ddl操作需要自己定制化操作

2、Debezium-postgresql参考：

计划：以触发器的形式对postgresql ddl做审计同步，将ddl操作审计记录到表，对表进行同步，完成ddl同步

create extension hstore;

create or replace function ef_alter() returns event_trigger as $$

declare

rec hstore;

begin

select hstore(pg_stat_activity.*) into rec from pg_stat_activity where pid=pg_backend_pid();

insert into aud_alter (ctx) values (rec);

$$ language plpgsql strict;

CREATE FUNCTION

testdb=# create event trigger e_alter on ddl_command_end when tag in ('ALTER TABLE') execute procedure ef_alter();

CREATE EVENT TRIGGER

testdb=# create table aud_alter(id serial primary key, crt_time timestamp default now(), ctx hstore);

CREATE TABLE

testdb=# create table test(id int);

CREATE TABLE

testdb=# alter table test alter column id type int8;

ALTER TABLE

testdb=# select * from aud_alter;
