Postgres is not closing JDBC connection .. Please help

Hello

I am using POstgres 7.3 and jdbc driver
org.postgresql.Driver.

I am using jdbc driver for PostgreSQL to connect to
the database and when I am closing the database
connection using Java but it seems PostgreSQL does not
close the connection actually. If the web page, which
uses the database connection, was visited
consecutively it freezes when trying to connect to the
database

Only solution is to shutdown Postgres Database and
restart it and it is not a very good solution.

Any Suggestion to clean jdbc connection in Postgres
database.

Thanks

Deepak

I think you should fix this in the java code, because PostgreSQL cannot
say goodye for the client. For example close connection in the "finally"
block, so it will be closed even if the code inside has a failure.

You've got that backwards: Java is not closing the Postgres connection.
You could be falling afoul of connection-pooling features in the JDBC
driver, perhaps.  Ask in the JDBC list if you need more help.
