Except for two different sorted (but correct) results while
selecting inherited tables in "misc", regression tests passed
with 2K.

Why shouldn't it work? All the catalogs that require really
big data have toast tables now.

Anyway, the 8K default BLCKSZ already restricts index tuples
to 2700 bytes. So I wouldn't recommend it at all.
