now accommodate an empty list as an instruction to not create/drop
any items, rather than ignoring the collection. [ticket:2664].
This is a behavioral change and extra notes to the changelog
and migration document have been added.

- [bug] Postgresql dialect memoizes that an ENUM of a

2011-10-29T21:38:56+00:00

particular name was processed
during a create/drop sequence.  This allows
a create/drop sequence to work without any
calls to "checkfirst", and also means with
"checkfirst" turned on it only needs to
check for the ENUM once.  [ticket:2311]

even if they are *not* restated.  its necessary here to do a "replacement"
scheme when an incoming sequence replaces the previous.  Theoretically
we could do what Table does here, i.e. use a singleton constructor, but
this is heavyhanded.   The most recent sequence placed in is the winner
is likely the most expected behavior.

including "checkfirst" logic.  [ticket:2055]
