What are common pitfalls when integrating PHP with PostgreSQL in forum software like phpbb?

Common pitfalls when integrating PHP with PostgreSQL in forum software like phpBB include not properly escaping user input, not utilizing prepared statements, and not handling database errors effectively. To solve these issues, always use parameterized queries with prepared statements to prevent SQL injection attacks, properly escape user input using functions like pg_escape_string, and handle database errors by checking for errors after each query execution. 

// Example of using prepared statements with PostgreSQL in PHP
$conn = pg_connect("host=localhost dbname=mydb user=myuser password=mypassword");

// Prepare a SQL query
$query = "SELECT * FROM users WHERE username = $1";
$stmt = pg_prepare($conn, "user_query", $query);

// Execute the prepared statement with user input
$username = pg_escape_string($_POST['username']);
$result = pg_execute($conn, "user_query", array($username));

// Check for errors and fetch results
if(!$result) {
    echo "Error executing query: " . pg_last_error($conn);
} else {
    while($row = pg_fetch_assoc($result)) {
        // Process the fetched data
    }
}

// Close the database connection
pg_close($conn);
