What did you do to the whitespace when posting that table? I had to
reformat it pretty heavily to understand what you had.
Anyway, I think the "mode" column should be right after the line number.
I assume the "reason" for skipped lines is going to be somewhere in the
table too.
What happens if a "reject" line is matched? I hope the lookup
would terminate there.
What does it mean to query for "all"? Do you have database and user
named "all"? Because otherwise that seems wrong to me; you should be
able to query for specific databases/users, but not for special
keywords; maybe I am wrong and there is a use case for this, in which
case please state what it is.
I see three problems in your code. One is that the translation of
auth_method enum to text should be a separate function, not the SQL
function layer; another is that the code to put keywords as JSON object
values is way too repetitive; the other is that messing with the JSON
API like that is not nice. (I don't think we're closed to doing that,
but that would be a separate discussion). I think this patch should
just use the "push value" interface rather than expose add_jsonb.
(I assume the usage of JSON rather than a regular array was already
discussed and JSON was chosen for some reason.)
