pglogical 2.3.2 on 9.4 --> 12.3 CONFLICT: remote DELETE (tuple not found). Resolution: skip.

a table has PK from multiple column (varchar(50),char(2),char(1)).

initial syncronization is OK, but when at source there is delete , but got error at target...

LOG:  CONFLICT: remote DELETE on relation public.a_XXXX replica identity index a_XXX_pk (tuple not found). Resolution: skip.

replica identity was set to default for the table so yes there is old image on those 3 columns:

but why delete was error at target?

collation exactly same on all GUC.

any direction to print debug verbosity on why delete on target didnt find row and skipped?
