Reverted. Rebasing notes:
1. Commit b4c9695e moved toast table declarations so I adapted to the
new scheme, but commit 0cc99327 had taken the OIDs that pg_collation
was previously using, so I had to pick some new ones from the
temporary range for later reassignment.
2. It took me quite a while to figure out that the collversion column
now needs BKI_DEFAULT(_null_), or the perl script wouldn't accept the
contents of pg_collation.dat.
3. In a separate commit, I rescued a few sentences of text from the
documentation about libc collation versions and reinstated them in the
most obvious place, because although the per-index tracking has been
reverted, the per-collation version tracking (limited as it is) is now
back and works on more OSes than before.
