This API has never been supported. Why do you use it when psqlODBC
returns info that it doesn't support SQLDescribeParam?

There is the problem that PgSQL backend doesn't support it before
execution (I haven't found another information yet).

Maybe you may depend on other information like PostgreSQL driver, ...

Sorry, I don't have one.
