Recognize unique indexes

Hello,
I'am using MSAccess 97 with Postgres 7.0x as
backend. ODBC driver parameter <Recognize unique
indexes> is set to on. When i link table as an ODBC,
access manager ask me for unique index for each table.
Why don't it recognize my table's primary or foreign keys
? I must set this manualy. I want to link table in VBA
code dynamicaly, but for this reason it is impossible
(when i do'nt set any field as index, i can't update any
table). What solution is for it?

With regards
