We cannot assume that zlib is available everywhere. Thus it
must be determined during configure and where it isn't, TOAST
can only move off values to make tuples fit into blocks.
Since decompression of already in memory items is alot faster
than doing an index scan on the TOAST table, I expect this to
make installations without zlib damned slow.

And how should binary distributions like RPM's handle it? I
assume that this problem is already on it's way because of
the integration of zlib into pg_dump. The only way I see is
having different RPM's for each possible combination of
available helper libs. Or is there another way to work
around?
