Handlind booleans Postgresql-Access

i created boolean in postgresql table (in attachment) but linked table in Access see this as short text. 

I checked in odbc option Bools as Char to false and True is -1 as true.but still tihs is not working.

I found linke here:

but this is very strange function there (which i am not understanding), why to use it? There is no other option?

Best,
