I believe this is a symptom of an old version of the jdbc driver. Perhaps
upgrading that would make this go away.

If you are creating a database from scratch why not create a brand new
database and drop the old one at some later point in time when no one is
connected. This has the additional benefit of the old db being availab
. Restarting tomcat
closes and reopens the connection to the database, so the query in the
procedure gets replanned to use the new index and things run smoothly.

bout this is the prototype for a function is
String exec(String []). So it's type checking certainly won't be
great. It says (and means) version 0.1 and doesn't (yet) deserve all the
noise it has caused.

all returned ERROR:

This is usually a symptom of not being in a transaction. Large objects
need to be done inside a transaction. Try adding
connection.setAutoCommit(false) somewhere in your code.

You may be confusing locale with encoding here. UTF-8 is an encoding not
a locale.

TIP 5: Have you checked our extensive FAQ?
e JDBC driver does support Statement.cancel(), but the tricky part is
that you need to have access to the Statement object that issued the
original query. You can't just open a new connection and cancel another
query.

h id 31.
If you had a table with an id column and 200 rows 1-200 you could do
SELECT MIN(idtab.id) FROM idtab LEFT JOIN realtab ON (idtab.id =
realtab.id AND realtab.id IS NULL)
A useful generic function would be one something like range(min,max) that
would return a set of rows so you wouldn&#x

grep VERSION conf
implementation (which is used for the group by)
has problems dealing with large numbers of similar values.
I think in later versions of pg our own qsort is used.

JDBC driver is a Type IV (pure java) driver.
Is this factor of 3 difference in time the difference from running psql
over unix sockets vs tcp, or is it the difference between a Java client
and psql? If it's the latter you'r

some data off disk and shovel it out over HTTP, consider how much more
work a database must do.
