Fujii-san, Thanks for your push! I've run regression tests on the HEAD and REL_1.2 branch and they have finished successfully. However, when I ran tests on REL_1.1 it failed because of the difference of 'pg_bigm.last_update'. -------------------------- diff -U3 /home/tori/pg_bigm/expected/pg_bigm.out /home/tori/pg_bigm/results/pg_bigm.out --- /home/tori/pg_bigm/expected/pg_bigm.out 2020-02-18 23:11:57.606388619 +0900 +++ /home/tori/pg_bigm/results/pg_bigm.out 2020-02-18 23:12:02.486400351 +0900 @@ -10,7 +10,7 @@ SHOW pg_bigm.last_update; pg_bigm.last_update --------------------- - 2016.10.11 + 2019.10.03 --------------------------- I think this difference has left since 2016.10.11, we don't need to care about this, do we?
