Consider upstream branch of migra

[ZakSingh]

Sadly it appears Migra is no longer maintained. It's missing quite a few features (namely: no support for composite types, comments, aggregate functions, function return type changes, partitions). There's an open PR that addresses these and adds some other fixes as well.

Would you ever consider switching to that Migra fork, or providing an option for it?

Yeah if it's demonstrated as better! Pull requests welcome :)
