 * and can be used to uniquely identify the connection within the server's process.

 * @param PgSql\Connection $connection The pg connection resource.
 * @return int The thread ID for the current connection.

/**
 * Returns whether the client library is thread-safe.
 *
 * This function is a wrapper for the pg_thread_safe function. It indicates whether the 
 * pg client library that PHP is using is thread-safe. This is important information when 
 * running PHP in a multi-threaded environment such as with the worker MPM in Apache or when
 * using multi-threading extensions in PHP.
 *
 * @return bool Returns TRUE if the client library is thread-safe, FALSE otherwise.
