Fix assorted bugs related to identity column in partitioned tables

Browse Source 
When changing the data type of a column of a partitioned table, craft
the ALTER SEQUENCE command only once.  Partitions do not have identity
sequences of their own and thus do not need a ALTER SEQUENCE command
for each partition.

Fix getIdentitySequence() to fetch the identity sequence associated
with the top-level partitioned table when a Relation of a partition is
passed to it.  While doing so, translate the attribute number of the
partition into the attribute number of the partitioned table.
