Hi
Itested my older patch for session variables with dedicated system catalog, and I was surprised so one independent test fails
src/test/modules/injection_points/expected/syscache-update-pruned.out
you can apply attached patch, and run test
# using temp instance on port 58928 with PID 422150
ok 1 - basic 82 ms
ok 2 - inplace 1556 ms
not ok 3 - syscache-update-pruned 719 ms
ok 4 - heap_lock_update 157 ms
1..4
# 1 of 4 tests failed.
