You have psql installed on your local(Windows?) machine?

Or are you using psql in your AWS instance?

all export file is store in c:\export\files\

To me the simplest solution would be to push the CSV files to the AWS
instance and work from there. The files will need to be run through a
Postgres command to be imported into a table.

Are you familiar with
COPY(https://www.postgresql.org/docs/12/sql-copy.html) or
\copy(https://www.postgresql.org/docs/12/app-psql.html)?

I can run \copy in Linux with individual csv file into the table fine

all csv files into one table is fine but each csv for each table. Should

Yes, you will need to copy each file into its own table.

Also, the problem is I can't pull/execute psql from window client to
pull the psql in aws instance and don't know how to create the batch
script for this run.  I tried simple \copy pull from c:\tes.csv and psql
is unknown.

There is no good/easy way I know of to install just psql on Windows. You
are better off copying the CSV files to the AWS instance.

Do you have PuTTY installed?:

https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

If not I would take a look at above link. PuTTY brings SSH to Windows.
The relevant part to this issue is:

https://the.earth.li/~sgtatham/putty/0.73/htmldoc/Chapter5.html#pscp

"PSCP, the PuTTY Secure Copy client, is a tool for transferring files
securely between computers using an SSH connection. "

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.

Also, the problem is I can't pull/execute psql from window client to pull

the psql in aws instance and don't know how to create the batch script for
this run. I tried simple \copy pull from c:\tes.csv and psql is unknown.

You cannot run psql without having it installed; there is a Windows
installer for PostgreSQL, so you could use that to get it installed.

Hopefully there is an installer that will just install PostgreSQL client
software (like psql, pg_dump, and notably *not* the database server
software); I don't use WIndows, so I am not too familiar with that.

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.

I understand your post about "password does not take an argument, it is

I used -W and --password=.  That's what I said I will try pgpassfile.
Thought it like mysq/oracle can indicate out without creating password
file.

If you want to expose your password in the script file then:

https://www.postgresql.org/docs/12/app-psql.html

Usage
Connecting to a Database

"An alternative way to specify connection parameters is in a conninfo
string or a URI, which is used instead of a database name. This
mechanism give you very wide control over the connection. For example:

$ psql "service=myservice sslmode=require"
$ psql postgresql://dbmaster:5433/mydb?sslmode=require

This way you can also use LDAP for connection parameter lookup as
described in Section 33.17. See Section 33.1.2 for more information on
all the available connection options."

So:

psql
postgresql://PSmasteruser:mypassword@hostname.amazonaws.com:5432/PSCIDR

or

psql 'dbname=PSCIDR user=PSmasteruser host=hostname.amazonaws.com port=
5432 password=mypassword '

Thank you again.
