16GB?!? Not unless your tuples are 8k. The 8k is/was the max _tuple_ size,
but more than one tuple can be stored per block. :)

Try the formula in the FAQ to get a reasonable estimate for the table's size.

If the patch I sent to PATCHES is applied, then it will be a compile-time setting
and you'll need a postmaster for each database w/differing block sizes. Not the
greatest solution, but it would work.

I almost have the "-k" option working today. Two files left to do...

backend/access/nbtree/nbtsort.c
backend/utils/adt/chunk.c

I'm being careful about pfree'ing all the stuff that I'm going to have to palloc.

Tiggers definitely do _not_ like memory leaks.
