Unable to insert UUID into PostgreSQL 13 database using PHP and PDO - php

Question

I am trying to use UUID's in postgres 13. I enabled the extension using the following code:
CREATE EXTENSION plpgsql;
CREATE EXTENSION "uuid-ossp";
Here is the code to create the table in postgres
CREATE TABLE IF NOT EXISTS customers.customers (
customer_id uuid DEFAULT uuid_generate_v4(),
title VARCHAR(10),
first_name VARCHAR(50) NOT NULL,
middle_name VARCHAR(50),
last_name VARCHAR(50) NOT NULL,
gender CHAR(1) NOT NULL,
date_of_birth date,
role_id INTEGER,
created_ts TIMESTAMP DEFAULT current_timestamp,
created_by VARCHAR(50) DEFAULT current_user,
updated_ts TIMESTAMP,
updated_by VARCHAR(50),
deleted_ts TIMESTAMP,
PRIMARY KEY (customer_id)
)
Here is the code I am using to insert the data into the table:
<?php
$uri = "POSTGRESQL_URI";
//$fields = parse_url($uri);
//echo $fields;
// build the DSN including SSL settings
$conn = "pgsql:";
$conn .= "host=" . '10.0.0.199'; //$fields["host"];
$conn .= ";port=" . '5432'; //$fields["port"];;
$conn .= ";dbname=savvywalletdb";
$conn .= ";sslmode=require"; // verify-ca:";
$conn .= ";sslcert=C:/MyData/Personal/Keys/client.crt";
$conn .= ";sslkey=C:/MyData/Personal/Keys/client.key";
$conn .= ";sslrootcert=C:/MyData/Personal/Keys/root.crt"; //ca.pem";
$db = new PDO($conn, "globoblanco", "Ntpxw!js9"); //$fields["user"], $fields["pass"]);
$db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_OBJ);
//SELECT * FROM pg_stat_ssl WHERE pid = pg_backend_pid()
foreach ($db->query("SELECT * FROM pg_stat_ssl") as $row) {
echo $row->version . PHP_EOL;
print($row->ssl . PHP_EOL);
}
$query = "SELECT uuid_generate_v4() as uuid";
$stmt = $db->prepare($query);
$stmt->execute();
$result = $stmt->fetch(PDO::FETCH_OBJ);
echo $result->uuid;
$title = 'Mr';
$first_name = 'Gabriel';
$middle_name = 'S';
$last_name = 'Lobo-Blanco';
$gender = 'M';
$date_of_birth = '10/14/1961';
$query = "INSERT INTO customers.customers (customer_id, title, first_name, middle_name, last_name, gender, date_of_birth) ";
$query .= " VALUES(':customer_id', ':title', ':first_name', ':middle_name', ':last_name', ':gender', ':date_of_birth')";
$stmt = $db->prepare($query);
$stmt->bindValue(':customer_id', $result->uuid, PDO::PARAM_STR);
$stmt->bindValue(':title', $title, PDO::PARAM_STR);
$stmt->bindValue(':first_name', $first_name, PDO::PARAM_STR);
$stmt->bindValue(':middle_name', $middle_name, PDO::PARAM_STR);
$stmt->bindValue(':last_name', $last_name, PDO::PARAM_STR);
$stmt->bindValue(':gender', $gender, PDO::PARAM_STR);
$stmt->bindValue(':date_of_birth', $date_of_birth, PDO::PARAM_STR);
$result = $stmt->execute();
Executing this code produces the following output:

The error in this output points to the following statement:
$stmt->bindValue(':customer_id', $result->uuid, PDO::PARAM_STR);
My assumption is that PHP does not support inserting UUID into postgres as I am not able to find a PDO type value I can use to match the table structure. I believe casting the UUID value generated to STRING type does not work because Postgres will check the value provided must match the column type which will cause the error.
I am thinking of a work around using stored procedures to perform the insert, but I was hoping to get a resolution to this issue without having to create that.
I am using PHP 8.2 and PostgreSQL 13.
Any suggestions anyone?
I tried using a PDO::PARAM_STR type to the bindValue() function but it does not seem to work.
The goal is to be able to execute the script and that it will perform a successful insert into the table.
