simple alter table add column hangs forever?

19.14 enterprise and multitenant

Linux

Hi,

This simple alter table commands hangs and never seems to finish:

ALTER TABLE USER.TABLE1 ADD PRINT_CODE VARCHAR(1 CHAR);

There are no locks on the table, its around 6000 rows. Query did not finish in 20 minutes.

Any ideas?
