PostgreSQL user default schema does not work

According to this documentation: https://confluence.atlassian.com/display/STASH/Connecting+Stash+to+PostgreSQL

PostgreSQL has the idea of schemas. When you create a PostgreSQL database, a 'public' schema is created and set as the default for that database. It is possible to create a different schema (e.g. 'stash') and set that as the default schema. Stash will use whatever schema is set as the default for the logged-in user. Stash does not provide a way for a user to nominate the schema to use; it uses schema that is set as the PostgreSQL default.

However, it will only work partially and Stash still trying to use other schema

Steps to reproduce

1. Run the following SQL queries:

   CREATE DATABASE atlassian WITH ENCODING='UTF8';
   CREATE USER conf WITH PASSWORD 'conf';
   CREATE SCHEMA AUTHORIZATION conf;
   

2. Connect a Confluence server to the database "atlassian" with user "conf"
   It will use the schema "conf"
3. Run the following SQL queries:

   CREATE USER stash WITH PASSWORD 'stash';
   CREATE SCHEMA AUTHORIZATION stash;
   

4. Connect a Stash server to the database "atlassian" with user "stash"
   The migration function in Stash will failed with the following error:

Checking the table in the schema "stash", the tables are created correctly. However, Stash is trying to access schema "conf" and the AO tables are missing too.
