Problem
Continued step 6 of the environments implementation plan.
#25600 added the
GroupTypeMapping.project
field, but existing group types still have a null value there.Changes
This sets
project
on everyposthog_grouptypemapping
record, and then makes the field non-nullable in two stages.Stage 1 – this PR:
NOT NULL
constraint is created withNOT VALID
so that the table is not locked.Stage 2 – follow-up PR #25876: We
VALIDATE
the constraint to enforce it in a non-locking way.The two stages must be in separate migrations to actually avoid locking.
