PostgreSQL and functional indexes

Reported by Mike Sidorov | January 12th, 2011 @ 12:16 PM

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 (Indexing using an arbitrary expression)

    This issue has been automatically marked as stale because it has not been commented on for at least three months.

    The resources of the Rails core team are limited, and so we are asking for your help. If you can still reproduce this error on the 3-0-stable branch or on master, please reply with all of the information you have about it and add "[state:open]" to your comment. This will reopen the ticket for review. Likewise, if you feel that this is a very important feature for Rails to include, please reply with your explanation so we can consider it.

    Thank you for all your contributions, and we hope you will understand this step to focus our efforts where they are most helpful.
