I have:

UNICODE db, 08.02.0004 which is unicode driver

I modify tables (a little bit):

>  "p_t_id" INTEGER,

>  "p_user" INTEGER DEFAULT 0 NOT NULL,

>  "p_date_add" TIMESTAMP WITHOUT TIME ZONE DEFAULT now() NOT NULL,
>  "p_date" TIMESTAMP WITHOUT TIME ZONE DEFAULT now() NOT NULL,
>  "p_status_deleted" SMALLINT DEFAULT 0 NOT NULL,

I remove this until end of definition becouse you don't specify the
boards table.

I'm unable to reproduce the error :-( Are you sure you use 08.02.0002 or
later psqlodbc driver? There is no ANSI x UNICODE version of the driver.

Could you try this VBS? Or could you specify one or two rows which
leads to error? Maybe length of text data could help ...
