Fix Syntax Error in CAST Statement for Postgres Attachment Count Query

[thienvu18]

When querying the Postgres database, the attachment count query was generated as follows:

select count(*) from "system_files" where "system_files"."attachment_id" = "CAST(some_table"."id" as "TEXT)" and "system_files"."attachment_type" = Some\Model and "field" = images) as "images_count"

This query results in a syntax error due to an incorrect placement of double quotes in the CAST statement.

Changes Made:
Fixed the syntax error by properly wrapping keys before casting.
Used raw queries to prevent issues with double wrapping of keys.

Thanks for the contribution @thienvu18! Any chance you're able to add a test case for this? Also, is this an issue that's present in Laravel as well?

Thank for your quick reply.

Sorry that I am not good at writing test cases. However, we can produce this bug using our Test Plugin as follows:

• Precondition: Using Postgres database
• Step 1: Add a Portfolio count column to user in file plugins/winter/test/models/user/columns.yaml

    portfolio_count:
        label: Portfolio count
        relation: portfolio
        useRelationCount: true

• Step 2: Access Users list at endpoint backend/winter/test/users. Open list setup then tick Portfolio count then Apply

Then you will get an exception like this

Notice at the generated sql statement, you will see an incorrect placement of quotes in the CAST statement

This bug only happens when using postgres database because Dongle will not cast if driver is not pgsql
