-- Annotate some tables in Postgres with a REPLICA IDENTITY.
|

|
-- Any table that doesn't have a primary key should be annotated explicitly with
|
||
|
-- a REPLICA IDENTITY so that logical replication can be used.
|
||
|
-- If this is not done, then UPDATE and DELETE statements on those tables
|
||
|
-- will fail if logical replication is in use.

|
-- See also: 82/04_replica_identities.sql.postgres on the main database

-- Where possible, re-use unique indices already defined on tables as a replica
|
||
|
-- identity.
