Avoid dropping Postgres schema
Browse files Browse the repository at this point in the history 
The postgres user needs to be an owner of the public schema or a
superuser in order to execute the schema.sql for database
initialization.

To avoid that, two changes are required:
 - use `CREATE TABLE IF NOT EXISTS` in order to idempotently create the
   necessary tables
 - handle conflicts when inserting duplicate data

This follows the pattern in use by the
src/main/resources/db/mysql/{data,schema.sql} files.
