Hmmm ... I'm wondering about version mismatches between your psql and
your backend.  Does "psql -V" agree with the backend version?

You can rebuild template1 from template0 (... that's pretty much why
template0 exists...).  There are some gotchas in this process, see this
link for a walkthrough:

However, I am not totally convinced that that's where your problem is.
Do you see failures when you are connected to other databases besides
template1?
