Just for the ones interested in a view on another turf: In Oracle "shutdown immediate" is the fastest _clean_ shutdown and "shutdown abort" is equal to "shutdown immediate" in PG. The other modes are called "shutdown normal" and "shutdown transactional".

I'm not necessarily opposed to commandeering the name "smart" for the new behavior, so that what we have to find a name for is the old "smart" behavior. How about slow - allow existing sessions to finish (old "smart") smart - allow existing transactions to finish (new) fast - kill active queries immediate - unclean shutdown regards, tom lane -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
