I thought that just checked cases where a bogus 'not a version' was put into 
pg_catalog.pg_depend.  I'm talking about having a collation provider who 
returns a different version string and has genuinely different collation rules 
between versions, thereby breaking the index until it is updated.  Is that 
being tested?
