# Test for bug #44738 "fill_schema_table_from_frm() opens tables without
# lowercasing table name". Due to not properly normalizing table names
# in lower_case_table_names modes in this function queries to I_S which
# were executed through it left entries with incorrect key in table
# definition cache. As result further queries to I_S that used this
# function produced stale results in cases when table definition was
# changed by a DDL statement. Also combination of this issue and a
# similar problem in CREATE TABLE (it also has peeked into table
# definition cache using non-normalized key) led to spurious
# ER_TABLE_EXISTS_ERROR errors when one tried to create table with the
# same name as a previously existing but dropped table.
