Bug description: memory leak in PDO::prepare while using pdo_pgsql
Description:
------------
Calling prepare() for pdo_pgsql connection consumes memory which is never
being freed. Specified query doesn't matter. It seems that this happen
because in my case pdo_pgsql does not use native prepared statements, but I
can't find the reason for this. I think so because calling prepare("foo")
does not cause an error as it does when I use pdo_mysql.
Reproduce code:
---------------
$a = new PDO('pgsql:'.$some_pdo_pgsql_dsn);
for ($i = 0; $i < 1000000; $i++)
{
$st = $a->prepare("");
print(memory_get_usage(true)."\n");
unset($st);
}
Expected result:
----------------
constant memory usage
Actual result:
--------------
increasing memory usage
