Re: create batch script to import into postgres tables

Thank you sir and I am sorry for the typo not having "--" on password.  I did spelling out with --password=mypassword
>> echo select count(*) from tableA; | "C:\Program Files\PostgreSQL\11\bin\psql" -U PSmasteruser -d PSCIDR -h hostname.amazonaws.com -p 5432 --password=mypassword

even -W for password>> echo select count(*) from tableA; | "C:\Program Files\PostgreSQL\11\bin\psql" -U PSmasteruser -d PSCIDR -h hostname.amazonaws.com -p 5432 -W=mypassword

none of them work, still prompt me for password to type in.  I will look into the pgpassfile which I know it will fail again.

very respectfully,

Once again -P has nothing to do with password. Also --password does not
take an argument, it is meant to be used as is. The purpose is to force
a password prompt. This is all spelled out here:

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

Also spelled out in above is:

" It is also convenient to have a ~/.pgpass file to avoid regularly
having to type in passwords. See Section 33.15 for more information."

And Section 33.15:

https://www.postgresql.org/docs/12/libpq-pgpass.html

"The file .pgpass in a user's home directory can contain passwords to be
used if the connection requires a password (and no password has been
specified otherwise).  ..."

Read more at link for how to do that.
