I found other answers were either not generic enough, or too complicated. Here is a simple one that should always work (for bootstrap 3):

$('[data-toggle="popover"]').each(function () {
    var button = $(this);
    button.popover().on('shown.bs.popover', function() {
        button.data('bs.popover').tip().find('[data-dismiss="popover"]').on('click', function () {
            button.popover('toggle');
        });
    });
});

Then just add attribute data-dismiss="popover" in your close button. Also make sure not to use popover('hide') elsewhere in your code as it hides the popup but doesn't properly sets its internal state in bootstrap code, which will cause issues next time you use popover('toggle').

Previous examples have two main drawbacks:

  1. The 'close' button needs in some way, to be aware of the ID of the referenced-element.
  2. The need of adding on the 'shown.bs.popover' event, a 'click' listener to the close button; which is also not a good solution because of, you would then be adding such listener each time the 'popover' is shown.

Below is a solution which has not such drawbacks.

By the default, the 'popover' element is inserted immediately after the referenced-element in the DOM (then notice the referenced-element and the popover are immediate sibling elements). Thus, when the 'close' button is clicked, you can simply look for its closest 'div.popover' parent, and then look for the immediately preceding sibling element of such parent.

Just add the following code in the 'onclick' handler of the 'close button:

$(this).closest('div.popover').popover('hide');

Example:

var genericCloseBtnHtml = '<button onclick="$(this).closest(\'div.popover\').popover(\'hide\');" type="button" class="close" aria-hidden="true">&times;</button>';

$loginForm.popover({
    placement: 'auto left',
    trigger: 'manual',
    html: true,
    title: 'Alert' + genericCloseBtnHtml,
    content: 'invalid email and/or password'
});

I was running into the problem of the tooltip doing some funky stuff when the close button became clicked. To work around this I used a span instead of using a button. Also, when the close button was clicked I would have to click the tooltip twice after it closed in order to get it to open again. To work around this I simply used the .click() method, as seen below.

<span tabindex='0' class='tooltip-close close'>×</span>

$('#myTooltip').tooltip({
    html: true,
    title: "Hello From Tooltip",
    trigger: 'click'
});    

$("body").on("click", ".tooltip-close", function (e) {
    else {
        $('.tooltip').remove();
        $('#postal-premium-tooltip').click();
    }
});

FWIW, here's the generic solution that I'm using. I'm using Bootstrap 3, but I think the general approach should work with Bootstrap 2 as well.

The solution enables popovers and adds a 'close' button for all popovers identified by the 'rel="popover"' tag using a generic block of JS code. Other than the (standard) requirement that there be a rel="popover" tag, you can put an arbitrary number of popovers on the page, and you don't need to know their IDs -- in fact they don't need IDs at all. You do need to use the 'data-title' HTML tag format to set the title attribute of your popovers, and have data-html set to "true".

The trick that I found necessary was to build an indexed map of references to the popover objects ("po_map"). Then I can add an 'onclick' handler via HTML that references the popover object via the index that JQuery gives me for it ("p_list['+index+'].popover(\'toggle\')"). That way I don't need to worry about the ids of the popover objects, since I have a map of references to the objects themselves with a JQuery-provided unique index.

Here's the javascript:

var po_map = new Object();
function enablePopovers() {
  $("[rel='popover']").each(function(index) {
    var po=$(this);
    po_map[index]=po;
    po.attr("data-title",po.attr("data-title")+
    '<button id="popovercloseid" title="close" type="button" class="close" onclick="po_map['+index+'].popover(\'toggle\')">&times;</button>');
    po.popover({});
  });
}
$(document).ready(function() { enablePopovers() });

this solution let me easily put a close button on all the popovers all across my site.

This is a working solution based on @Chris answer above, but fixed so that upon subsequence clicks of the trigger element, you don't have to click the element twice.

Using .popover('hide) manually messes up bootstraps internal state, as noted in the comments.

var closePopover = function(eventShown) {
   // Set the reference to the calling element
   var $caller = $('#' + this.id);

   // Set the reference to the popover
   var $popover = $('#' + $(eventShown.target).attr('aria-describedby'));

       // Unbind any pre-existing event handlers to prevent duplicate clicks
       $popover.find('.popover-close').off('click');

       // Bind event handler to close button
       $popover.find('.popover-close').on('click', function(e) {

          // Trigger a click on the calling element, to maintain bootstrap's internal state
          $caller.trigger('click');
        });
 }

$('.popoverTriggerElement').popover({
   trigger: 'click'
})
.on('shown.bs.popover', closePopover)

Now, you can use the close button without duplicating the click events, and keeping bootstraps internal state in check so it works as expected.

The trick is to get the current Popover with .data('bs.popover').tip():

$('#my_trigger').popover().on('shown.bs.popover', function() {
    // Define elements
    var current_trigger=$(this);
    var current_popover=current_trigger.data('bs.popover').tip();

    // Activate close button
    current_popover.find('button.close').click(function() {
        current_trigger.popover('hide');
    });
});
