PostgreSQL provider has MySQL provider metadata when dll installed

[jng]

When you install the PostgreSQL provider using the provider registry API, it is installed into providers.xml with MySQL provider metadata.

Re-opening.

The cause is that the PostgreSQL provider is providing the MySQL provider message catalog ids when resolving localizable strings.

[jng]

In 8261:

Use correct message ids for PostgreSQL provider
