# This is not a test of FTS5, but rather a test of the of what happens to
# prepared statements that encounter SQLITE_SCHEMA while other prepared
# statements are running. The original problem POC used FTS5, and so
# is seems reasonable to put the test here.
#
# The vdbeaux24.test module in TH3 also tests this same behavior but
# without requiring FTS5 or an other extension.
