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.
Is this planned ?
