Re: Unique key constraint Issue

Output should be consistent across servers below query o/p

SELECT conname, pg_get_constraintdef(oid)
FROM pg_constraint
WHERE conrelid = 'your table name'::regclass AND contype = 'u';
(different datatype combine in UK is not an issue). This issue may not
happen in asynchronous, log shipping or streaming replication. In logical
replication it may create problem.
