For "finish" I mean get out of space (in other write-heavy tables) or high
CPU usage (due to slow index scan checking the same rows again and again).
Also, you REPACK one table - and add a lot of bloat in others, in some
cases with negative impact in total.
But yes, agree about pg_squeeze here - if it is usable with such a long
transaction - REPACK CONCURRENTLY will be too.
