-#
-# EVIDENCE-OF: R-44697-61543 If SQLITE_OMIT_TRIGGER is defined but
-# SQLITE_OMIT_FOREIGN_KEY is not, then SQLite behaves as it did prior to
-# version 3.6.19 - foreign key definitions are parsed and may be queried
-# using PRAGMA foreign_key_list, but foreign key constraints are not
-# enforced.
-#
-# Specifically, test that "PRAGMA foreign_keys" is a no-op in this case.
-# When using the pragma to query the current setting, 0 rows are returned.
-#
-# EVIDENCE-OF: R-22567-44039 The PRAGMA foreign_keys command is a no-op
-# in this configuration.
-#
-# EVIDENCE-OF: R-41784-13339 Tip: If the command "PRAGMA foreign_keys"
-# returns no data instead of a single row containing "0" or "1", then
-# the version of SQLite you are using does not support foreign keys
-# (either because it is older than 3.6.19 or because it was compiled
-# with SQLITE_OMIT_FOREIGN_KEY or SQLITE_OMIT_TRIGGER defined).
