I get this part that separates SQL script for import each table,
(import.sql)
begin;
\copy table_1 (c1, c2, c3) from '/path/tabledata1.csv' csv header;
commit;
\copy table_1 (c1, c2, c3) from '/path/tabledata1.csv' csv header;
commit;
In oracle I created a shell script with all oracle_sid, oracle_home, and read the function/procedure... for psql, especially from window client, I did put psql_home and connect to the instance, it failed
c:\Progra~1\PostgreSQL\11\bin\psql -d PSCIDR -h localhost -p 5432 -U postgres -i import.sql
even I do a simple count
c:\Progra~1\PostgreSQL\11\bin\psql -d PSCIDR -h localhost -p 5432 -U postgres -c "select count(*) from tableA";
none of them is work. Try to learn how to execute its script.

Create a file with commands in it like the example from Christopher
Browne that was posted earlier:
"There is no single straightforward answer to that.
Supposing I want a batch to either all be processed, or to all not process,
then I might write a sql file like:
begin;
\copy table_1 (c1, c2, c3) from '/path/tabledata1.csv' csv header;
\copy table_2 (c1, c2, c3) from '/path/tabledata2.csv' csv header;
\copy table_3 (c1, c2, c3) from '/path/tabledata3.csv' csv header;
commit;
But you may be fine with having a separate SQL script for each table.
There will be conditions where one or the other is more appropriate, and
that will be based on the requirements of the process."
Then point psql at it:
psql -d some_db -h some_host -U some_user -f the_file
Be aware that \copy is all or nothing. If there is a single failure in
the copying the whole copy will rollback. Given that the one file per
table might be preferable.
