I can reproduce the issue on a v10 server, for example:
=# create temporary table foo ( bar int generated by default as identity ) on
commit drop;
CREATE TABLE
=# \q
$ psql
=# create temporary table a (b varchar);
ERROR:  XX000: could not open relation with OID 16389

Perhaps you did not start with a fresh server or did not reset the
connection properly?  This counts.
