Hi list,
I found a memory leak in the pgsql driver that is not fixed in CVS.
Here is a patch:
--- drivers/pgsql/dbd_pgsql.c.orig 2006-09-20 12:07:39.000000000 +0200
+++ drivers/pgsql/dbd_pgsql.c 2006-09-20 12:35:06.000000000 +0200
@@ -543,8 +543,10 @@
int dbd_ping(dbi_conn_t *conn) {
PGconn *pgsql = (PGconn *)conn->connection;

- PQexec(pgsql, "SELECT 1");
+ res = PQexec(pgsql, "SELECT 1");
+ if (res) PQclear (res);
if (PQstatus(pgsql) == CONNECTION_OK) {
return 1;
In addition, it would be nice if you could incorporate the following
patch, as this makes the pgsql driver compatible with the Redhat 9
supplied postgresql 7.3 (yes it is old, but it is still used by NASA for
the project I am working on):
