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).
