We could have a section for transaction-related parameters, and move
the vacuum ones into the section for autovacuum so as they get
grouped, renaming the section "autovacuum and vacuum". An idea of
group for search_path, temp_tablespace, default_tablespace & co would
be "object parameters", or "relation parameters" for all the
parameters which interfere with object definitions?
