(FlywaySqlException in Spring) Password authentication failed for user - spring

Question

I try to connect my Spring-Boot-Application with new PostgreSQL USER (named : localX_deletion), but when i run it, that return me FlywaySqlException :
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is org.flywaydb.core.internal.exception.FlywaySqlException:
Unable to obtain connection from database: FATAL: password authentication failed for user "localX_deletion"
SQL State : 28P01 Error Code : 0 Message : FATAL : password authentication failed for user "localX_deletion"
I dont understand because i can connect with this user in command-line : psql -U localX_deletion -h localhost and when i specify in spring.datasource another account the application run as excepted.
How i create Database/Role:
CREATE USER localx_deletion;
CREATE DATABASE localx_deletion OWNER localx_deletion;
ALTER USER localx_deletion WITH ENCRYPTED PASSWORD 'localx_deletion';
ALTER DATABASE localx_deletion OWNER TO localx_deletion;
GRANT ALL PRIVILEGES ON DATABASE localx_deletion TO localx_deletion;
What i have already tried to fix it:
For each tasks bellow i have restart postgresql service.
Update password/name role.
Delete all and re-create all.
Setting in pg_hba.conf local and host as trust (that works but i dont like update this file, because the old config work fine with the others roles/databases).
Purge, remove and reinstall Postgresql
Someone have an idea for fix it please ?
