Uh, how big is that database exactly?

One question is, if migration is so painful, why are you updating to a
branch that is already obsolete? At this point you should be skipping
8.1.x and going directly to 8.2.x; or maybe planning to wait a few more
weeks and go to 8.3.x. I say this not just on general principles, but
mindful of the fact that there were some pretty significant improvements
in sorting speed in 8.2, which would translate directly to shorter btree
index build times. (Are all your indexes btrees?)

Also, are you following the guidelines at

?
