Hm, I'm not sure that's much better than the existing wording.  The
bigger point here though is that if we consider this to be a user-facing
error case, it ought to be ereport not elog.

I checked what you get for the normal non-extension case:

regression=# set search_path = bogus;
SET
regression=# create table t1 (f1 int);
ERROR:  no schema has been selected to create in
regression=# \set VERBOSITY verbose
regression=# create table t1 (f1 int);
ERROR:  3F000: no schema has been selected to create in
LOCATION:  RangeVarGetCreationNamespace, namespace.c:485

Seems like we ought to use the same message (and SQLSTATE) as in
namespace.c, since nobody's complained about that one.
