Er, make that 8K.  If the limit were 8Meg, a lot fewer people would be

Huh?  I assume you're talking about an array of float4 (or float8).
That's going to be 4 (or 8) bytes per value internally, zero or not.

Maybe you are thinking of the external textual representation of the
array.

Offhand I'm not sure.  I don't see any obvious restriction in copy.c,
but there could be lurking problems elsewhere.  Have you tried it?
