In 959f6d6a1821 it seems that I fat-fingered and missed a newline in the usage
output, which makes --check become appended to -B rather than on its own line.
The attached diff fixes that.

Dear Hackers.
Currently, the XLogWrite function is written in 8k(or 16kb) units
regardless of the size of the new record.
For example, even if a new record is only 300 bytes, pg_pwrite is
called to write data in 8k units (if it cannot be writing on one page
is 16kb written).

Bonjour Michaël,
So I'll set out to write and use "pg_strtou?int64", i.e. 2 functions, and
then possibly generalize to lower sizes, 32, 16, depending on what is
actually needed.
I am interested in this patch, and the next commit fest is close by.
