Andrew Dunstan 6d12b68cd7 Allow IF NOT EXISTS when add a new enum label. 
If the label is already in the enum the statement becomes a no-op.
This will reduce the pain that comes from our not allowing this
operation inside a transaction block.

Andrew Dunstan, reviewed by Tom Lane and Magnus Hagander.
