for pg_dump it is: PostgreSQL 10.1, compiled by Visual C++ build 1800, 64-
bit
for pg_restore it is the same machine as well as newest version of
Postgresql 12, so I assume the error is in pg_dump.

selects work no problem, I even dumped one table with COPY and it doesnt
raise any issue. The other table however is probably too big to ever do
this. 

schema for one table: 

CREATE TABLE table1 (

    foreign_id integer,

    action character varying(10),

    numarr smallint[]

);

and other table:

CREATE TABLE log (

    id integer NOT NULL,

    place character varying(50),

    place_no integer,

    "time" character varying(80),

    action character varying(100),

    "user" character varying(50),

    place_definition character varying(10),

    place_definition2 character varying(50),

    place_definition3 character varying(30)

);

Which Postgres version of pg_dump/pg_restore are you using to do above?

What happens if you SELECT from these tables in the Postgres 10 instance?

Can you show the schema definition for one or more of the problem tables?
