Hi John, IIRC you can force PostgreSQL (or any other DB really) to treat column names as case-sensitive by including them in double quotes when creating and querying the tables. In Cayenne this means setting "Quote SQL Identifiers" to "on" in the DataMap and using explicit double quotes in SQLTemplate.
Not going to help with "SELECT * FROM", but should address all other cases. > Like forcing or providing a switch to ensure DbAttribute names are > lowercase? If the above doesn't help, you can probably decorate DataMapLoader service to conditionally convert loaded DataMap to lower case DbAttributes (if you can access DataSource and determine DB type prior to project loading), or do that in the EntityResolver after ServerRuntime startup (less clean, but same end result).
