# Test organization:
#
# pragma-1.*: Test cache_size, default_cache_size and synchronous on main db.
# pragma-2.*: Test synchronous on attached db.
# pragma-3.*: Test detection of table/index inconsistency by integrity_check.
# pragma-4.*: Test cache_size and default_cache_size on attached db.
# pragma-5.*: Test that pragma synchronous may not be used inside of a
#             transaction.
# pragma-6.*: Test schema-query pragmas.
# pragma-7.*: Miscellaneous tests.
# pragma-8.*: Test user_version and schema_version pragmas.
# pragma-9.*: Test temp_store and temp_store_directory.
# pragma-10.*: Test the count_changes pragma in the presence of triggers.
# pragma-11.*: Test the collation_list pragma.
# pragma-14.*: Test the page_count pragma.
# pragma-15.*: Test that the value set using the cache_size pragma is not
#              reset when the schema is reloaded.
# pragma-16.*: Test proxy locking
