我的版本使用第一个，有一些错误检查…

BEGIN;
CREATE OR REPLACE FUNCTION reset_sequence(_table_schema text, _tablename text, _columnname text, _sequence_name text)
RETURNS pg_catalog.void AS
$BODY$
DECLARE
BEGIN
 PERFORM 1
 FROM information_schema.sequences
 WHERE
  sequence_schema = _table_schema AND
  sequence_name = _sequence_name;
 IF FOUND THEN
  EXECUTE 'SELECT setval( ''' || _table_schema || '.' || _sequence_name  || ''', ' || '(SELECT MAX(' || _columnname || ') FROM ' || _table_schema || '.' || _tablename || ')' || '+1)';
 ELSE
  RAISE WARNING 'SEQUENCE NOT UPDATED ON %.%', _tablename, _columnname;
 END IF;
END; 
$BODY$
 LANGUAGE 'plpgsql';

SELECT reset_sequence(table_schema, table_name, column_name, table_name || '_' || column_name || '_seq')
FROM information_schema.columns
WHERE column_default LIKE 'nextval%';

DROP FUNCTION reset_sequence(_table_schema text, _tablename text, _columnname text, _sequence_name text) ;
COMMIT;

克劳斯的答案是最有用的，除了有一点遗漏:你 必须在select语句中添加DISTINCT。

但是，如果您确定没有表+列名是等价的 对于两个不同的表，您还可以使用:

select sequence_name, --PG_CLASS.relname, PG_ATTRIBUTE.attname
       reset_sequence(split_part(sequence_name, '_id_seq',1))
from PG_CLASS
join PG_ATTRIBUTE on PG_ATTRIBUTE.attrelid = PG_CLASS.oid
join information_schema.sequences
     on information_schema.sequences.sequence_name = PG_CLASS.relname || '_' || PG_ATTRIBUTE.attname
where sequence_schema='public';

哪个是user457226的扩展方案适用的情况下 一些感兴趣的列名不是“ID”。

重新检查公共模式函数中的所有序列

CREATE OR REPLACE FUNCTION public.recheck_sequence (
)
RETURNS void AS
$body$
DECLARE
  _table_name VARCHAR;
  _column_name VARCHAR;  
  _sequence_name VARCHAR;
BEGIN
  FOR _table_name IN SELECT tablename FROM pg_catalog.pg_tables WHERE schemaname = 'public' LOOP
    FOR _column_name IN SELECT column_name FROM information_schema.columns WHERE table_name = _table_name LOOP
        SELECT pg_get_serial_sequence(_table_name, _column_name) INTO _sequence_name;
        IF _sequence_name IS NOT NULL THEN 
            EXECUTE 'SELECT setval('''||_sequence_name||''', COALESCE((SELECT MAX('||quote_ident(_column_name)||')+1 FROM '||quote_ident(_table_name)||'), 1), FALSE);';
        END IF;
    END LOOP;   
  END LOOP;
END;
$body$
LANGUAGE 'plpgsql'
VOLATILE
CALLED ON NULL INPUT
SECURITY INVOKER
COST 100;

只需运行以下命令:

SELECT setval('my_table_seq', (SELECT max(id) FROM my_table));

还有另一个plpgsql -仅当max(att) >时重置lastval

do --check seq not in sync
$$
declare
 _r record;
 _i bigint;
 _m bigint;
begin
  for _r in (
    SELECT relname,nspname,d.refobjid::regclass, a.attname, refobjid
    FROM   pg_depend    d
    JOIN   pg_attribute a ON a.attrelid = d.refobjid AND a.attnum = d.refobjsubid
    JOIN pg_class r on r.oid = objid
    JOIN pg_namespace n on n.oid = relnamespace
    WHERE  d.refobjsubid > 0 and  relkind = 'S'
   ) loop
    execute format('select last_value from %I.%I',_r.nspname,_r.relname) into _i;
    execute format('select max(%I) from %s',_r.attname,_r.refobjid) into _m;
    if coalesce(_m,0) > _i then
      raise info '%',concat('changed: ',_r.nspname,'.',_r.relname,' from:',_i,' to:',_m);
      execute format('alter sequence %I.%I restart with %s',_r.nspname,_r.relname,_m+1);
    end if;
  end loop;

end;
$$
;

另外注释行——execute format('alter sequence将给出列表，而不是实际重置值

把它们放在一起

CREATE OR REPLACE FUNCTION "reset_sequence" (tablename text) 
RETURNS "pg_catalog"."void" AS
$body$
DECLARE
BEGIN
  EXECUTE 'SELECT setval( pg_get_serial_sequence(''' || tablename || ''', ''id''),
  (SELECT COALESCE(MAX(id)+1,1) FROM ' || tablename || '), false)';
END;
$body$  LANGUAGE 'plpgsql';

将修复给定表的'id'序列(通常在django中是必要的)。
