The patch I posted definately fixes a bug. Not sure how I missed the
regression changes caused by not migrating sequences; I thought it was
an issue with cached sequence values, not an actual bug.
However, I with the patch, I am now seeing another difference; a
database with:
SELECT pg_catalog.setval('clstr_tst_a_seq', 33, true);
becomes:SELECT pg_catalog.setval('clstr_tst_a_seq', 33, false);
and the is_called column of the migrated sequences is NULL:
regression=> \d check_seq Sequence "public.check_seq" Column | Type |
Value---------------+---------+---------------------sequence_name | name | check_seq last_value | bigint | 1
start_value | bigint | 1 increment_by | bigint | 9223372036854775807 max_value | bigint | 1 min_value |
bigint | 1 cache_value | bigint | 1 log_cnt | bigint | 25387551686656 is_cycled | boolean | f is_called

regression=> select * from check_seq where is_called is null; sequence_name | last_value | start_value |
increment_by |max_value | min_value | cache_value | log_cnt | is_cycled

Something is certainly wrong. Did we change sequence table format from
8.3 to 8.4?
