Postgres bpchar Default Value Throwing Error

I have generated a migration from a postgres source but when I try to import that xml migration into a new database I have errors with bpchar columns:

[ERROR] Reason: liquibase.exception.DatabaseException: ERROR: syntax error at or near “N”

[ERROR] Position: 163 [Failed SQL: CREATE TABLE my_table (id BIGSERIAL NOT NULL, group_id BIGINT NOT NULL, award_id BIGINT NOT NULL, archived BPCHAR(1) DEFAULT ‘‘N’::bpchar’ NOT NULL, time_created TIMESTAMP WITH TIME ZONE DEFAULT NOW() NOT NULL, time_modified TIMESTAMP WITH TIME ZONE DEFAULT NOW() NOT NULL)]

Here is what the xml looks like:

The defaultValue is being quoted when it imports (it is adding single quotes around it). Is there any way to ask liquibase to NOT add quotes around the default value?

I forced the defaultValue to defaultValueNumeric but I am not sure if that is the proper solution.
