Suppose I have a large table with no indexes, and I scan the entire thing. What is the impact on the shared buffers? I'm interested in three scenarios: - Scan done in SQL using SELECT, (via JDBC if it matters). - Scan done using SQL COPY. - Scan done using psql COPY. I suspect that the SELECT scan will tend to displace everything else in shared buffers, and I hope that the two forms of COPY do not. Is that correct? I'm using 7.4 now, but I'm also interested in the answer for 8.x. Morris ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
