Could someone tell me where the above doc come from ?
Certainly both windows-ODBC and unixODBC need odbcinst.ini
but I couldn't find *odbcinst* in any iODBC doc/src.
In fact psqlodbc driver works with iODBC without odbcinst.ini.
I'm not familiar with ODBC under unix and am happy if someone
explains it.

No psqlodbc really uses ODBCINST_INI under Windows and probably
under unix also. I could see
getGlobalDefaults(DBMS_NAME, ODBCINST_INI, FALSE)
in psqlodbc.c and environ.c.

Yes you are right.
There must be a documentation about how to let
the psqlodbc driver work with iDOBC though I don't
know who could do it. And someone should improve gpps.c.
