Need help migrating MSSQL2008R2 tables into PGSQL & make PGSQL mimic MSSQL behaviour.

I heard PGSQL can act like MSSQL behaviour so I'm trying to migrating tables to try it myself, but I really have hard time to migrating them. I already looked https://wiki.postgresql.org/wiki/Microsoft_SQL_Server_to_PostgreSQL_Migration_by_Ian_Harding but nothing is useful. For example, "Extension Links" section links are all PAID links. I have *.MDF and *.ldf MSSQL2008R2 DATA files. Can anyone please give me a command to how to migrate those data? I do not have MS' graphic studio GUI but I can access this database using "Navicat Lite"(IP:Port login).
How many tables do you have, and what are their sizes? I'm asking because if you're considering migrating to PostgreSQL, starting from scratch might be cleaner. This approach will also help you gain a deeper understanding of how data types are handled in PostgreSQL compared to MSSQL.

I think you have heard about Babelfish (https://babelfishpg.org/). It is a modified version of PostgreSQL, written by Amazon, that provides a TDS interface to PostgreSQL, so that a program written for Microsoft SQL Server can connect to it. It works up to a certain extent. You could use it to migrate data to PostgreSQL, but you'd have to continue to use Babelfish unless you change your application to speak the PostgreSQL protocol. There are other tools to migrate to PostgreSQL, for example https://github.com/fljdin/mssql_migrator Yours, Laurenz Albe
