That's it! It takes exactly 8 seconds like my program.
I retrieve the data through a bound column:
SELECT * FROM tblItem WHERE intItemIDCnt = ?
After converting this to
SELECT * FROM tblItem WHERE intItemIDCnt IN (...)
the query is as fast as psql: 409ms
So the problem is identified and the solution is to recode my application.

PS: When enabling UseDeclareFetch as suggested by Tom then the runtime is
still three times slower: 1192ms. But I guess that problem is for the ODBC
list.
