PostgreSQL compatibility: the PgServer was not working properly when the setting database_to_upper was set to false.

JdbcDataSource: the methods setUrl and getUrl where added as aliases for setURL and getURL. This should solve problems with the HikariCP (Hikari connection pool).

H2 Console: when loading the schema, incorrect JDBC calls where issued, which caused the exception "Column PRECISION not found".

Slightly reduce the memory cost of View metadata, helps with people who have lots and lots of views, and there is no real performance gain in caching the plan SQL string

The collation can now be set in the database URL, even if there are data tables, if the collection is the same as the current collation.

Added support for ON DUPLICATE KEY UPDATE like MySQL with the values() function to update with the value that was to be inserted.
Patch from Jean-Francois Noel.

Issue 517: Create or replace view statement has no effect on the others already existing JDBC connection    

Issue 518: java.sql.Connection.commit() freezes after LOB modification with EXCLUSIVE connection    

Improve error message when dropping an index that belongs to a constraint, specify constraint in error message.

For in-memory databases, queries with a "group by" column that is also a hash index threw a RuntimeException.
