I suggested it not for performance, but for simplicity of code. So if we still need it, I agree to leave it. Moreover, LP_DELETEed tuples might be useful for Bitmap NOT And/Or join, not only maintenance operations. Union-side of bitmap should not contain LP_DELETEed tuples, and Except-side should do. --- ITAGAKI Takahiro NTT Cyber Space Laboratories ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
