Hi!
With InnoDB tables under 3.23.4x, if you perform an ALTER TABLE on
a table, any foreign key declarations that point to that table fail
to work (they always return a failure).
Is this a known bug? I don't see it on the InnoDB todo or bug
list, but I seem to remember hearing about it

Hrmm. Is that a feature that's planned to be fixed. Obviously,
if you have a table with thousands or millions of rows in it, ALTER
TABLE is a lot easier than copying the table to a temp table,
dropping the original table, creating a new table, and copying the
data back in.
Actually,

Hi!
Use SELECT INTO OUTFILE + READ DATA INFILE
Do not rename tables.
