I have 8.3 database with non-trivial table (~ 80million rows, but the
rows are just two integers).
I need to add not null on one of the columns, but it seems to require
full table scan.
I tried with some indexes, but I can't get the time to something
reasonable, so here is my question: is there any way I could make the
"not null" constraint *fast*?
i need it to be able to run pg_reorg on this table, which requires pkey,
or unique index on not-null column.
Best regards,
depesz
