Get list of subscribers with non-normalized tags on active accounts
Investigating the impact of the new Tag Normalization rules on existing subscribers on active accounts.
Gathering data
I imported a dump of the subscriber_tags
table from AppDB as well as the
list.subscribers
table data for all active accounts (~SELECT s.* FROM
list.subscribers s JOIN accounts a ON (a.a_id = s.account_id) WHERE a.status_id
< 7~)
I then built a table of subscribers having tags that do not match our validation rules.
CREATE TABLE invalid_tags AS
SELECT s.list_id, s.account_id, t.subscriber_id, tag
FROM subscribers s
JOIN subscriber_tags as t ON (s.id = t.subscriber_id)
, unnest(tags) tag
WHERE tag != normalize_tag(tag)
