I will clarify a little here. The only way to fix this is to add new
code to REL_17_STABLE for pg version >= 170000 and < 170003.
Something like, "if postgresql in pg 17 with bug in
pg_get_constraintdef, do not call pg_get_constraintdef for contype =
'n', but describe it using pg_dump code"
This is a very difficult solution to maintain in-core, so the only
advice I can give is no actually update the minor version of the
server.
