* Improve speed with indexes

  For large table adjustments during VACUUM FULL, it is faster to cluster
  or reindex rather than update the index.  Also, index updates can bloat
  the index.

schema.relation, because the notify code only honors the relation name.
schema.relation will now generate a syntax error.

Check length of enum literals on definition and input to make sure they will fit in a name field and not cause syscache errors.

return void ends with a SELECT, if that SELECT has a single result that is
also of type void.  Without this, it's hard to write a void function that
calls another void function.  Per gripe from Peter.

Back-patch as far as 8.0.

If either of these "can't happen" errors actually happened, we'd freeze up
trying to acquire an already-held lock.  Latest word is that this does
not explain Martin Pitt's trouble report, but it still looks like a bug.

pg_valid_server_encoding() returns the same result if the encoding is
valid.

its table list and then rechecks pgstat before vacuuming each table to
verify that no one has vacuumed the table in the meantime.

In the current autovacuum world this only means that a worker will not
vacuum a table that a user has vacuumed manually after the worker started.
When support for multiple autovacuum workers is introduced, this will reduce
the probability of simultaneous workers on the same database doing redundant
work.
