[OSSTEST PATCH 5/7] mg-schema-test-database: posgtres compat: Sequences

[Ian Jackson <iwj@xxxxxxxxxxxxxx>]

Now (postgresql 11) start_value is in a different table.  We don't
really care about it very much and mostly care about the last value,
so we fix that (and launder the for-db comparison dumps).
