No. I don't plan on locking the table at all. The only thing that is changed during the initial fast-build-index is that new tuples are inserted after CTID_INDEX_MIN, and after the initial fastbuild index is done, the only restriction is that the index can't be used in queries before the tuples between CTID_INDEX_MIN and CTID_INDEX_MAX are added to the index. As the number of tuples between CTID_INDEX_MIN and CTID_INDEX_MAX is finite, they must be added in finite time, by which time the index will be up-to-date and usable for querie planner. (i.e. (1) is done) All tuples inserted after the initial fast-build-index has finished and CTID_INDEX_MAX is fixed, are inserted into the index at the time of inserting the tuple, like for any other index. -- Hannu Krosing <[EMAIL PROTECTED]> ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
