Sounds like you didn't do the rebuild correctly. The full recipe is

1. Change BLCKSZ in include/config.h (after running configure).
2. Do a *full* compilation. If you compiled already, do "make clean"
before "make all". Do not rely on make dependencies, because there
aren't any.
3. Install.
4. initdb.

No. Page size is a pretty fundamental thing...
