by any chance did you create the extension in the template1 database?

The whole extension is not in template1, else "CREATE FROM unpackaged"
would have worked.  But evidently there are at least some conflicting
objects there.  I speculate that somebody installed a pre-9.1 version of
the extension in template1, realized their mistake, and then tried to
clean it out manually (piecemeal) instead of using the uninstall script.
And missed some things.

Anyway the solution is to connect to template1 and drop any cruft that's
lying around in it.

I am the user who has the situation - the background is:

- the previous installation on Fedora 14 x86_64 was PostgreSQL 8.x

- there were old (unused) versions of LedgerSMB

- during the move from Fedora 14 to Fedora 16 (x86_64), the data was
dumped out of PG 8.x and restored to PG 9.1P

I haven't done any manual messing around with template1 as far as I
know . .

Regards,

Phil.

Well, the behavior you describe indicates pretty strongly that there are
some non-factory-standard objects in template1.  If the database is a
few years old, that's not exactly hard to believe --- all it takes is
one time having connected to the wrong place and created some stuff.
Just go have a look and get rid of what you find ...
