	-- Many of the following columns should be non-nullable, but were originally

	-- missing them. Unfortunately, it is unfeasible to retroactively fill missing
	-- values with defaults and add the constraints as there are simply too many
	-- rows in production.

	-- For similar legacy reasons, many fields that should have type BIGINT are TEXT.

	join_server_enabled BOOLEAN,
	join_server_channel TEXT,
	-- This column should be a TEXT[]. But for legacy reasons, it is instead a single
	-- TEXT column containing all template responses joined together and delimited by
	-- the character U+001E (INFORMATION SEPARATOR TWO.)

-- Tables created with gorm have missing NOT NULL constraints for created_at and
-- updated_at columns; since these columns are never null in existing rows, we can
-- retraoctively add the constraints without needing to update any data.

-- Now the more complicated migration. For legacy reasons, the general_notification_configs
-- table previously contained two pairs of columns for join and leave message:
--   * join_server_msg, join_server_msgs_
--   * leave_msg, leave_msgs_
-- all of type TEXT. (The variants with _ were added when multiple-response support was
-- implemented and contain the individual responses separated by U+001E as described
-- previously.)

-- Ideally, we only have one column for each message. We achieve this state with the following
-- multi-step migration:
--   1. Update old records with join_server_msg != '' or leave_msg != '' to use the plural
--      join_server_msgs_ and leave_msgs_ columns respectively.
--   2. Drop the join_server_msg and leave_msg columns.
--   3. Rename join_server_msgs_ to join_server_msgs and leave_msgs_ to leave_msgs.

-- Here goes.
