Are
you using the Postgres JDBC driver? Or are you using an ODBC JDBC
driver? The Postgres specific driver is usually
faster.

What happens if you do this by declaring it as a cursor and then

I do executeQuery(), for the resultSet I do next() and return one row,

A good short test is to run explain analyze on the query from the psql
command line. If it shows an execution time of significantly less than
what you get from you application, then it is likely that the real
problem is that your application is receiving the whole result set via
libpq and waiting for that. A cursor will solve that problem.

TIP 4: Have you searched our list archives?

Yes, the difference between psql command line and
application is 6 seconds to 40 seconds. It is
exactly the step resultSet =
excecuteQuery() that needs 40 seconds. I use next() as a cursor
through the
resultSet, but I fear this is not enough, do I have to use
createStatement(resultSetType,
resultSetConcurrency) respectively
prepareStatement (resultSetType, resultSetConcurrency) to
achieve the
cursor behaviour?
