A bunch of errors show up with postgres-direct/stat-logical-repl.sh script

here's some:

SELECT
    active, inactive_since, invalidation_reason, wal_status,
    confirmed_flush_lsn, pg_wal_lsn_diff(pg_current_wal_lsn(), confirmed_flush_lsn)
    FROM pg_replication_slots WHERE slot_name = '_planetscale_import';
ERROR:  column "inactive_since" does not exist
LINE 2:     active, inactive_since, invalidation_reason, wal_status,
                    ^

INSERT 0 1

ERROR:  relation "_planetscale_import" does not exist
LINE 1: SELECT * FROM _planetscale_import WHERE ts >= 1758815025;
# script exits

Start with postgres-direct/stat-logical-repl.sh and reproduce the two reported PostgreSQL errors: the missing replication-slot column and the missing _planetscale_import relation on the replica. Trace the script's setup and test-record steps; done means the script completes without those errors and the inserted record is visible on the replica.
