Answer 1

Maybe you are creating table using quote like "BATCH_JOB_INSTANCE". Also check is schema is specified in datasource.url since you don't use schema name in query.

Answer 2

Thanks Abinash for great help. I simply reverse Primary and Secondary. It worked.

# Datasource - Secondary
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/program?currentSchema=BATCH
spring.datasource.username=postgres
spring.datasource.password=admin
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

# Postgres - Primary
spring.hello.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.hello.datasource.url=jdbc:mysql://localhost:3306/test
spring.hello.datasource.username=root
spring.hello.datasource.password=root

#spring.batch.table-prefix=batchmetadata.BATCH_
spring.batch.initialize-schema=always
spring.batch.job.enabled=false

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl

Also, using below worked.

writer.setSql("INSERT INTO \"BATCH\".customer VALUES (:id, :firstName, :lastName, :birthdate)");
