innobase_rename_column_try(): When renaming SYS_FIELDS records for secondary indexes, try to use both formats of SYS_FIELDS.POS as keys, in case the PRIMARY KEY includes a column prefix. Without this fix, an ALTER TABLE that renames a column followed by a server restart (or LRU eviction of the table definition from dict_sys) would make the table inaccessible. |
