api-pls postgres schema

If all of the tables created by api-pls are in a schema, then they wouldn't interfere with existing tables.

---

Anytime a sync or migration occurs, I can ensure the schema exists via:

`CREATE SCHEMA IF NOT EXISTS api_pls`

Then, I can create tables in that schema via

`CREATE TABLE api_pls.my_table`

Start by locating the sync and migration entry points that create api-pls tables. Check how CREATE SCHEMA IF NOT EXISTS api_pls and schema-qualified table creation would fit there, then verify that existing tables are not affected and that migrations and syncs work when the schema is absent.
