Re: Cancelled Vacuum Leaving Tables Locked?

I think I've seen this, or something similar...when I was doing a CREATE
INDEX on a huge table and cancelled it, but there was still a postmaster
process running on the server doing CREATE, and the table was still locked.
I did everything short of 'kill -9' to the process, and it ignored me....I
checked back several hours later and it was gone...probably finished with
the CREATE and exited.

Incidentally, can someone tell me what happens when you do a CREATE INDEX or
a VACUUM ANALYZE? It seems like it should be a O(n) type operation, yet it
seems to take an excessively increasing long time as table size grows, like
O(n^2) or something...
