-- This migration checks for the type of the `locked` column
|
|
-- before applying the migration is due to an edge case. The
|
|
-- edge case is:
|
|
-- 1. User is using v1 hasura with no event triggers
|
|
-- 2. User upgrades to v2, since there are no event triggers in the metadata, source catalog migrations won't be run.
|
|
-- 3. User downgrades from v2 to v1, now since the 41_to_42 migration is
|
|
-- moved to `pg_source_migrations/0_to_1.sql` the
|
|
-- `hdb_catalog.event_log` exists as of the catalog version of v1.3.3,
|
|
-- which means we would be trying to downgrade something which was
|
|
-- never upgraded.
