Before this fix, the performance schema tables were defined in UPPERCASE. This was incompatible with the lowercase_table_names option, and caused issues with the install / upgrade process, when changing the lower case table names setting *after* the install or upgrade. With this fix, all performance schema tables are exposed with lowercase names. As a result, the name of the performance schema table is always lowercase, no matter how / if / when the lowercase_table_names setting if changed.
