After some research:

I found solutions.

Find the details of docker image.

%>  docker ps -a --filter "name=docker-compose"

%>. CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
b5b26f985       postgres:12.3       "docker-entrypoint.s…"   5 hours ago         Up 19 minutes       5432/tcp            docker-compose

Get into image environment

%> docker exec -it b5b26f985 bash 

%>root@b5b26f985:/# ls
root@b5b26f985:/# bin  boot  dev  docker-entrypoint-initdb.d  docker-entrypoint.sh  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var

now connect to PG

root@b5b26f985e9b:/# psql -h localhost -U <username >

<username >=# select * from DATABASECHANGELOGLOCK;
 id | locked |       lockgranted       |          lockedby          
----+--------+-------------------------+----------------------------
  1 | t      | 2020-06-18 11:36:08.825 | 85c1e0340e82 (172.18.0.12)
(1 row)

Description of table locked type my change form system to system and DB to DB so so good to check the data type.

<username >=# \d DATABASECHANGELOGLOCK;
                    Table "public.databasechangeloglock"
   Column    |            Type             | Collation | Nullable | Default 
-------------+-----------------------------+-----------+----------+---------
 id          | integer                     |           | not null | 
 locked      | boolean                     |           | not null | 
 lockgranted | timestamp without time zone |           |          | 
 lockedby    | character varying(255)      |           |          | 
Indexes:
    "databasechangeloglock_pkey" PRIMARY KEY, btree (id)

Update query

=# update DATABASECHANGELOGLOCK set LOCKED=false, LOCKGRANTED=null, LOCKEDBY=null where ID=1;

UPDATE 1
<username >=# SELECT * FROM DATABASECHANGELOGLOCK;
 id | locked | lockgranted | lockedby 
----+--------+-------------+----------
  1 | f      |             |

--Try now this should work . Happy coding.
