Comment (by Algunenano):

 > It means upgrades would fail, doesn't it ?

 Obviously not, since people have already migrated from 2.5 to 3.0. It was
 handled using `./postgis/postgis_before_upgrade.sql` and that's still in
 place, so upgrades that require changing the signature from `geom1` to
 `line1` don't fail.

 Again, the issue here is that 3.0+PG11 -> 3.0+PG12 was changing the
 signature from the new one to the old one (due to this bug) and we don't
 have a way to handle this explicit change, but we do handle the change
 from the old signature to the new one.
