Issue while connecting PostgreSQL 13 with Tableau 2020.3 & even applying COPY statement on PGAdmin

Hi Team,

Please help me in connecting PostgreSQL with Tableau.

*Error:*

*An error occurred while communicating with PostgreSQLUnable to connect to
the server. Check that the server is running and that you have access
privileges to the requested database.Error Code: 37CE01A3authentication
method 10 not supportedUnable to connect to the PostgreSQL server
"localhost". Check that the server is running and that you have access
privileges to the requested database.*

This is impacting the business. As a lot of data is in the database and
Tableau makes it difficult to work.
Please resolve it as soon as possible.

*For more details, I am sharing the screenshot of error generating while
connecting with PostgreSql.*

I'm also facing problem in COPY statement while inserting multiple data via
csv file in PGAdmin.
Again, showing same error.
"Access Priviledges"

Please solve this issue as soon as possible.
