BUG #7581: changing blocksize makes tests fail

The following bug has been logged on the website:

Bug reference: 7581
Logged by: William Dauchy
Email address: wdauchy@gmail.com
PostgreSQL version: 9.2.1
Operating system: Linux
Description:

I tried to compile pgsql9.2 with the following options: --with-blocksize=16
and --with-wal-blocksize=16.

Some tests failed. I didn't have the issue with pgsql9.1.

Could someone confirm the issue?

select_views ... FAILED
========================
1 of 132 tests failed.
