Fails: MySQL -- generateChangeLog -- liquibase to PostgreSQL

I use the liquibase command-line script with “generateChangeLog” to export a schema from MySQL to a change-log file.

I then try to use that to seed a database in PostgreSQ, again with the command-line script, now with “update”. It fails with:

   ERROR: syntax error at or near “UNSIGNED”

I assumed that the change-log XML was database-agnostic as long as I stay away from elements. Is this not correct?
