# tries to load any unloaded schemas for both the new database and any
# already attached databases (including the main database). If it is
# unable to load any such schemas, then the ATTACH statement fails.

# This block tests that if the loading of schemas as a result of an
# ATTACH fails due to locks on the schema table held by other shared-cache
# connections the extended error code is SQLITE_LOCKED_SHAREDCACHE and
# it is possible to use the unlock-notify mechanism to determine when
# the ATTACH might succeed.
