Hello,
Depending on your web development environment (java, php, .NET) etc, you should be able to use some mechanism that will provide a pool of connections to the database. Each request does not open a new connection (and then release it), but insteads gets a connection from the pool to use, and returns it back to the pool when done.
Where can I find some examples for connection pooling with php? Or must I just use persistence connections?
php handles connection pooling more or less automatically ... as long as you use pg_pconnect() instead of pg_connect().
You have to be careful using connection pooling. For example, if you create a temporary table and forget to delete it when the the script completes, the next time the script runs, it's likely that the connection will be reused and the script will cause an error because the temp table already exists.
Gavin Sherry added the ON COMMIT DROP clause to CREATE TEMPORARY TABLE in 7.4 which, depending upon the expected life-cycle of the temporary table, may prove useful in the above scenario.
FWIW,
