There are various applications where we want to completely replace the
contents of a table with new/re-calculated data.
It seems fairly obvious to be able to do this like...
1. Prepare new data into "new_table" and build indexes
2. Swap old for new
BEGIN;
DROP TABLE "old_table";
ALTER TABLE "new_table" RENAME to "old_table";
COMMIT;
Step (2) works, but any people queuing to access the table will see
ERROR: could not open relation with OID xxxxx
Could we make that work without error?
