[PostgreSQL] Can't properly use multi wiki when not on public schema

My postgresql installation for xwiki do not use public schema. Instead I've got a custom schema, that I set on xwiki.db property in xwiki.cfg, and in liquibase.properties (schemaName:  XXX)

When I try to create a separate wiki, xwiki will successfully create the schema for the another wiki, but this schema will remain empty with no tables, and the documents will be created in the main schema, resulting in severable problems. This make multi wiki unusable in this configuration
