pgsql: Revert "Add eager and lazy freezing strategies to VACUUM."

Revert "Add eager and lazy freezing strategies to VACUUM."

This reverts commit 4d417992613949af35530b4e8e83670c4e67e1b2. Broad
concerns about regressions caused by eager freezing strategy have been
raised. Whether or not these concerns can be worked through in any time
frame is far from certain.
