I had this problem with 8.4->9.2 upgrade recently.
It is not documented, but postgis 1.5.8 is the only version, that is
compatible with all the pg versions from 8.3 to 9.2, so you could use
pg_upgrade with it.
So here is the solution:
1. on pg 8.3 you need to soft upgrade [1] postgis from 1.3.x to 1.5.8 first;
2. then pg_upgrade 8.3 to 9.2;
3. and then you will have to do hard upgrade [2] postgis from 1.5.8 to 2.0.4.
