postgres backend processes

Hi!

I'm accessing a database using JDBC. My Java code for a query typically
looks like:

        Statement sta = con.createStatement();
         sta.executeQuery( "SELECT * FROM TABLE" );

For some reason, the postgres daemon that gets forked on the DB
server (Solaris 2.6, postgresql 7.2) keeps growing the number of processes
for each query
that I execute, until it hangs up. Is there something I'm
doing wrong in my queries, or is there a patch for this?

Thanks for any help,

regards,
Álvaro Matos.
