Subject: [PATCH v1 1/2] docs: Include database collation check on SQL from
 ALTER COLLATION

Previously the alter_collation.sgml documentation section include a SQL
that can be used to identity all collations in the current database that
need to be refreshed due to a collation version miss match and the
objects that depend on them. However if there is objects that use the
database collation these objects are not returned by the query.

This commit improve the query on alter_collation.sgml to include the
database collation version check too to report such cases.
