align postgresql native id generation with hibernate (sequence)

[zyro23]

using an id generation "native" with postgresql, hibernate defaults to using one hibernate_sequence.

liquibase-hibernate uses autoincrement in a hardcoded way: https://github.com/liquibase/liquibase-hibernate/blob/master/src/main/java/liquibase/ext/hibernate/snapshot/ColumnSnapshotGenerator.java#L162

why is that behavior needed? or could the defaults be aligned?
