Specify the postgres executable, instead. Note the > warning: core file may not match specified executable file. > Core was generated by `/usr/pgsql_src/postgresql-8.3.3/src/test/regress/tmp_check/install/usr/local/pg'. though this is evidently getting confused by the overly long path, so you might still see the warning even after picking the right executable. regards, tom lane
