	I kinda like this one...if it can be relatively implimented.  The main
reason I like it is that, like -B and -S, it means that someone could deal
with "tweaking" a system without having to recompile from scratch...

	That said, I'd much rather that -k option being something that is 
an option only available when *creating* the database (ie. initdb) with a
pg_blocksize file being created and checked when postmaster starts up.

	Essentially, make '-k 8192' an option only available to the postgres
process, not the postmaster process.  And not settable by the -O option to
postmaster...

	See above...it should only be something that is settable at initdb time,
not accessible via 'postmaster' itself...
