Peter Eisentraut a11c9c42ea Check collation when creating partitioned index 
When creating a partitioned index, the partition key must be a subset
of the index's columns.  But this currently doesn't check that the
collations between the partition key and the index definition match.
So you can construct a unique index that fails to enforce uniqueness.
(This would most likely involve a nondeterministic collation, so it
would have to be crafted explicitly and is not something that would
just happen by accident.)

This patch adds the required collation check.  As a result, any
previously allowed unique index that has a collation mismatch would no
longer be allowed to be created.
