Re: [SQL] Howto to force NULL rows at the bottom ? - Mailing list pgsql-sql

Always test everything you say. The NULLs will come out at the end no
matter which way you order it. There is a TODO item for this, but I
suspect that the function manager clean up needs to be completed first,
because there are a lot of subtle and not so subtle problems with NULLs
all over the place.
