Same problem with adding rs.close() :
sQLStatement.setInt(1, 2602);
rs = sQLStatement.executeQuery();
rs.close();
sQLStatement.setInt(1, 2604);
rs = sQLStatement.executeQuery();
rs.close();
sQLStatement.setInt(1, 2605);
rs = sQLStatement.executeQuery();
rs.close();

In eclipse Helios profiler, Jdbc3ResultSet live instances
increase (and never decrease). Same thing with
org.postgresql.core.v3.QueryExecutorImpl$ErrorTrackingResultHandler
and org.postgresql.core.v3.QueryExecutorImpl$1 classes.
f_transite stored procedure make some select, insert and update.
If you need more explanation, i can give it to you.
Java 6
postgresql-9.0-801.jdbc3.jar
PostgreSQL 8.2.5 on powerpc-apple-darwin8.8.0, compiled by GCC
powerpc-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer,
Inc. build 5363)
Is it a memory leak ? Or my java code is wrong ?
