Problemas con insert php + postgres

[spike01]

Hola me dedico a uds con la posibilidad de ke me ayuden a encontrar el posible error en este script de insert este es mi codigo:

<?php
$insertSQL = "INSERT INTO doctores(docNo_d, ape1_d, ape2_d, nom_d, rprof_d, dir_d, tel_d, mov_d, email_d, consultorio_d, id_esp_mg) ";
$insertSQL .= "VALUES ( '" .$docNo_d. "', '" .$ape1_d. "', '" .$ape2_d. "', '".$nom_d. "', '" .$rprof_d. "', '" .$dir_d. "', '" .$tel_d. "', '" .$mov_d. "', '" .$email_d. "', '" .$consultorio_d. "', '" .$id_esp_mg. "' )";

$Result1 = pg_exec($HC,$insertSQL) or die(pg_result_error());
echo "<script language=javascript>alert('Datos insertados con Exito!!');</script>";
?>

y esta mi bd en postgres:

CREATE TABLE doctores
(
foto bytea,
"docNo_d" bigint NOT NULL DEFAULT nextval('"doctores_docNo_d_seq"'::regclass),
ape1_d character varying,
ape2_d character varying,
nom_d character varying,
rprof_d character varying,
dir_d character varying,
tel_d bigserial NOT NULL,
mov_d bigserial NOT NULL,
email_d character varying,
consultorio_d numeric,
id_esp_mg serial NOT NULL,
CONSTRAINT doctores_pkey PRIMARY KEY ("docNo_d"),
CONSTRAINT doctores_id_esp_mg_fkey FOREIGN KEY (id_esp_mg)
REFERENCES especialidad_mg (id_esp_mg) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
WITHOUT OIDS;
ALTER TABLE doctores OWNER TO postgres;


este es el error ke me sale:

Warning: pg_exec(): Query failed: ERROR: column "docno_d" of relation "doctores" does not exist at character 22 in c:\appserv\www\hc\html\doctor1.php on line 23

le estare agradecido por cualkier posible solucion; estare pendiente a sus comentarios.

Gracias de antemano
