How to do sharding on schema using yaml?

[DeoLeung]

Hi, we have a postgres database for multi-tenant using schema, the tables will look like

• schema_1.user
• schema_2.user
• ...
• schema_100.user
• public.some_other_tables

we want to separate them to databases:

• db_a
  • schema_1.*
  • schema_2.*
• db_b
  • schema_3.*
  • schema_4.*
• db_fallback (everything not in db_a and db_b)
  • schema_5.*
  • ...
  • schema_100.*
  • public.*

since 5.1.2 supports schema, is there any example yaml config for it?
