Suppose a web application with persistent database connections.
I have some queries which take longer to plan than to execute !
I with there was a way to issue a PREPARE (like "PERSISTENT PREPARE").
Now all Postgres connections would know that prepared statement foo(
$1, $2, $3 ) corresponds to some SQL query, but it wouldn't plan it yet.
Just like a SQL function.
When invoking EXECUTE foo( 1,2,3 ) on any given connection the
statement would get prepared and planned. Then on subsequent invocations
I'd just get the previously prepared plan.
How would that be different from the current PREPARE/EXECUTE? Do you
mean you could PREPARE in one connection, and EXECUTE in another? If
you're using persistent connections, it wouldn't be any faster than
doing a PREPARE once in each connection.
