Postgresql does not support Transaction in the same way mssql, it does support nesting transactions in a limited way from version 11+

https://docs.microsoft.com/en-us/sql/t-sql/functions/trancount-transact-sql?view=sql-server-ver15

https://www.postgresql.org/docs/current/sql-begin.html

https://wiki.postgresql.org/wiki/Autonomous_subtransactions

https://www.postgresql.org/docs/11/sql-createprocedure.html

https://severalnines.com/database-blog/overview-new-stored-procedures-postgresql-11

From version 11 and up we have Procedures it supports commit and rollback transaction inside a PROCEDURE and must be called with CALL, there are no savepoints or transaction naming support...

There are work around this problem using PlPython, or FDW to callback to postgresql creating a new session to create independent Transactions..
