5e59e543d6 Additional fix to upgrade script
Drop old "repl_events" table.

4f6b642320 Fix extension script for unpackaged upgrades to 5.2
Apparently "ALTER TABLE" (which we were using to convert the
"repl_events" table) does not mark the table as being part of the
extension. Instead, we need to create the new table and copy the
data, as is done with the other tables.
