Did you try re-installing postgis 1.5.x ?

Excellent. It should even fail with a clear message about why
it was wrong to try that and what to do instead (did it?).

Good. How did you do that ?

Ouch. This shouldn't have happened.
Could you please file a ticket for this ?

It's in the README file, under the section UPGRADING:
<< PostGIS provides a SOFT UPGRADE procedure for minor or bugfix releases,
and an HARD UPGRADE procedure for major releases. >>
Maybe it isn't clear how to distinguish a "minor or bugfix" release
from a "major" release ?
