That's a well known, long standing problem which is still not
fixed in v6.5. I'm planning to fix it for v6.6 - though that
doesn't help you.

Never did it, but the BLCKSZ is defined in include/config.h.
That is a file generated from config.h.in, so be sure to
change it there and reconfigure before recompiling.
And if you change the blocksize, be sure to run initdb after
because your databases will not be binary compatible any
more!
