Hm, which database(s) did you check in?  It certainly appears from the
dump text you quote that type "spheroid" has OID 1407909 in at least one
database.

If I'm reading you right, then these must be instances of the same type
with the same OID declared in different databases.  Could you look through
the dump for \connect commands to verify that?

Could you look at the text surrounding these places to determine which
types this OID is being selected for?  Each of these calls should be just
preceding a CREATE TYPE command (with maybe a set_next_array_pg_type_oid
call between) that is supposed to use the specified OID for its type.
Also identify which databases the commands are being issued in, by looking
back for the most recent \connect command.

Also, is there any CREATE TYPE for st_envelope preceding the failing
CREATE FUNCTION command (in the same database)?
