I get this part that separates SQL script for import each table,

but when open the psql sql shell script it prompts line by line for
localhost, port, db, user, and password. If I set up a script and let
it run it won't connect to the postgresql instance. I want to know how
to execute a batch script connect to the database/instance.
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
The above should be -f import.sql. AFAIK there is no -i for psql, so
that should be failing.
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";
psql -d production -U postgres -c 'select count(*) from cell_per';
Null display is "NULL".
count
-------
68
(1 row)
psql -d production -U postgres -c 'select count(*) from cell_per'
Null display is "NULL".
count
-------
68
psql -d production -U postgres -c 'select count(*) from cell_per;'
Null display is "NULL".
count
-------
68
none of them is work. Try to learn how to execute its script.
What error messages do you get?

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.
