thank you,   I tried that too, remove the quote around the echo and it prompt 
for password, as I mentioned no matter I put -P mypassword no matter what I 
spell out password=mypassword still argument error
>>echo select count(*) from tableA; | "C:\Program Files\PostgreSQL\11\bin\psql" 
>>-U PSmasteruser -d PSCIDR -h hostname.amazonaws.com -p 5432  

>> echo select count(*) from tableA; | "C:\Program 
>>Files\PostgreSQL\11\bin\psql" -U PSmasteruser -d PSCIDR -h 
>>hostname.amazonaws.com -p 5432 password=mypassword
all usernames are same password.
thank you so much for all input.

No one in this world is pure and perfect.  If you avoid people for their 
mistakes you will be alone. So judge less, love, and forgive more.To call him a 
dog hardly seems to do him justice though in as much as he had four legs, a 
tail, and barked, I admit he was, to all outward appearances. But to those who 
knew him well, he was a perfect gentleman (Hermione Gingold)

Remove the quotes around echo

echo select count(*) from web_20200619; | "C:\Program 
Files\postgresql\11\bin\psql" -d *** -h *** -U ***

or, store your query into a text file and use 

psql -f query.sql

thank you for the link.  I did try it and it's still error

This is getting old. The error is?

I can run 'psql -u postgres -d PSCIDR -p 5432' (on Linux server, still learning 
how to run it from psql shell in Window) fine from psql prompt.  Just still 
wonder how to connect directly to the instance PSCIDR from scripting in both 
aws and linux.  Otherwise manually run using pgAdmin.
