I'm investigating linting SQL files in a project. sqlfluff seems good and I'm keen to get it integrated into the pre-commit checks for the project I'm working on.
However, the linter is currently producing false positives for any parameter use in parameterised SQL.

To select the postgres dialect:
sqlfluff lint --dialect postgres database_query.sql
This should accept named parameters without complaining.
The default dialect (at the point of writing) is ansi
