Hi Pascal,

Do you mean the sample program that acts as the application, do you want me
to share that? I can do that, but I guess my post will get blocked.

Yes, c1 is the PK. Pls see below:
bmdb=# desc dept_new
      Table "public.dept_new"
 Column |     Type      | Modifiers
 c1     | numeric(10,0) | not null
 c2     | numeric(10,0) |
 c205   | numeric(10,0) |
    "dept_new_pkey" PRIMARY KEY, btree (c1)


We dont analyze after loading the table. But I guess thats required only if
the query plan is in doubt, lets say its doing a full table scan or alike,
isnt it? That is not the case. The query is using PK index but it just
seems to be slow.
