relation doesnt exist when creating postgres database from spring
1
I want to automatically create postgres database schema on startup of spring application.
I'm manually creating an empty database from pgadmin and when I'm running my spring application for first time I get this error log:
full log
Basically main errors are:
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "alter table day_places drop constraint FKscp1fnpwfhy14rf7tiur81akl" via JDBC Statement
Caused by: org.postgresql.util.PSQLException: ERROR: relation "day_places" does not exist

Caused by: org.postgresql.util.PSQLException: ERROR: relation "nights_places" does not exist
As I notice the errors are only about fields of classes which I have annotated as @onetomany.
Even though these errors are displayed, the tables are still created and used as expected.
After first running, these errors are not displayed anymore, But I want to still solve these. So how to create these relations on startup? any help will be appreciated

I want to automatically create postgres database schema on startup of spring application.
I'm manually creating an empty database from pgadmin and when I'm running my spring application for first time I get this error log:
full log
Basically main errors are:
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "alter table day_places drop constraint FKscp1fnpwfhy14rf7tiur81akl" via JDBC Statement
Caused by: org.postgresql.util.PSQLException: ERROR: relation "day_places" does not exist

Caused by: org.postgresql.util.PSQLException: ERROR: relation "nights_places" does not exist
As I notice the errors are only about fields of classes which I have annotated as @onetomany.
Even though these errors are displayed, the tables are still created and used as expected.
After first running, these errors are not displayed anymore, But I want to still solve these. So how to create these relations on startup? any help will be appreciated
