Thread: pgsql: backpatch "Set application_name per-test in isolation and ecpg t

backpatch "Set application_name per-test in isolation and ecpg tests."

We started to backpatch test infrastructure improvements more aggressively to
make it easier to backpatch test. A proposed isolationtester improvement has a
dependency on b1907d688, backpatch b1907d688 to make it easier to subsequently
backpatch the new proposed isolationtester change.
