The error you see in that situation is:

postgres-2015-05-27 06:25:10.173 PDT-0ERROR:  relation "table1" already
exists
postgres-2015-05-27 06:25:10.173 PDT-0STATEMENT:  create table table1 (i
int);


Best guess is as Pete and Albe said, some user code is directly
accessing pg_class or the index has been corrupted.
