Had to change setup_redsys because admins can not read the current
encrypt key, thus it is not possible to `set encrypt_key =
coalesce(…, encrypt_key)`.
Not that it did much sense, anyway, as i was already inside the branch
of the if when encrpty_key is null.
However, it seems that this also affects in the `on conflict` update. I
assume this is because `excluded` is some kind of row of the relation
and has the same restrictions.
I want these because when there are changes in the signature i then have
to find where it is used, and it is easier to do when the compiler tells
you.
For relations it is less necessary because GoLand knows how to validate
SQL strings for them, but it seems to not work with functions,
apparently due to the lack of the “FROM” keyword.
Besides, it tx.FunctionName(ctx, params...) is shorter than
tx.Exec("select functions_name($1, $2…)", params...).
