I'm asking you not to be condescending with people who come to this mailing list with a problem. Not all the members on this lists senior postgres architects, some are just normal users.
sorry if that came across as condescending. It wasn't meant as such.
My idea for this "nonsense" switch just was a workaround for bad designed databases schemas or for compatibility reasons with rarely used closed source applications, such as Microsoft Access.
In my opinion such broad "switches", that then silently mangle over all data, are dangerous at best.
Where is the difference between truncating a number and truncating a date to stop PostgreSQL from complaining about February 31st when importing data from MySQL? Or a switch for the Oracle FDW to replace NUL bytes in VARCHAR2 columns with \x00 sequences?
The only difference I can see is that one is out of PostgreSQL, the other two are into.

Access 2010 at least can handle a precision of 28 digits.

I don't think that the database design is broken, since PostgreSQL supports NUMERIC columns without a specific precision. So all I can do is: create a VIEW, which rounds or casts my data on the fly to a format, Access can access via the ODBC driver.
