PostgreSQL and functional indexes

#6282

I have a table with functional index with the following DDL

`CREATE INDEX "index_company_tokens_on_email_ci" ON "public"."company_tokens"
  USING btree ("company_id", (lower((email)::text)));

When I try to run tests, I get the following

PGError: ERROR:  zero-length delimited identifier at or near """"
LINE 1: ...y_tokens_on_email_ci" ON "company_tokens" ("company_id", "")
: CREATE  INDEX "index_company_tokens_on_email_ci" ON "company_tokens" ("company_id", "")

    It's not ActiveRecord issue. You should use config.active_record.schema_format = :sql when using expressions like (lower((email)::text)).

    You would also take a look at https://github.com/mlomnicki/redhillonrails_core (Indexing using an arbitrary expression)
