To my understanding, the REFRESH statements "merely" update
the version information stored in the related objects. They
do not change anything else; and the REINDEX does not
reference them in any way.
I suppose the REINDEX goes first as it does the actual fixing
of now-invalid objects by rebuilding them. After that one is
back to a usable database state, even if left with pesky
(albeit harmless) warnings on version mismatches -- which to
get rid of one runs the REFRESH statements.
Or so my understanding...
Which is why my question still stands: does the above
three-strikes operation safely take care of any collation
issues that may currently exist in a database ?
