This appears to be the same issue as CORE-2753, except that I am trying to specify defaultValueNextSequence when defining the table rather than in the alter table.
The resulting error is:
I've tried various combinations instead of just 'deadlineIds':
deadlines.deadlineIds -> gets quoted as [deadlines.deadlineIds]
[deadlines].[deadlineIds] -> gets quoted as [[deadlines].[deadlineIds]]
It also appears that defaultValueSequenceNext is not documented in https://www.liquibase.org/documentation/column.html
