How to copy all tables from one database to another in postgres

My requirement is to copy all tables and not the database (SID, SCHEMA) from one database to another on postgres.

Below is the command to copy single table from a database to another database.

pg_dump -U Username -h DatabaseEndPoint -a -t TableToCopy SourceDatabase | psql -h DatabaseEndPoint -p portNumber -U Username -W TargetDatabase
What would be the command to copy not one but all tables and their contents from one database to another in postgres?

I'm using postgres 12.
