patch from dbd_pgsql_close function:
275 if (dbd->conn !=3D NULL) {
276 #if defined(DEBUG) && !defined(_WIN32)
277 PQuntrace(dbd->conn)=3B
278 #endif
279 PQfinish(dbd->conn)=3B
280 dbd->conn =3D NULL=3B
281 }
282 FREE(dbd)=3B
283 dbd =3D NULL=3B
IHMO=2C the caller of PQfinish can=B4t call twice.
Best regards=2C
