Add support for socket based connections in PostgreSQL
Remove useless text
Value should be a js string but was not being encoded as such.
init
use the correct dbo
Remove new lines
Fixing tag routing
first,  is sometimes an integer so don't json encode it then. Second, if it's not an integer, it might be a string with unwanted leading spaces so trim it, and json_encode it. Third, it's going in an html attribute so escape the quotes and any other special characters.
remove core.js
[#5424] - /modules/mod_articles_category/helper.php and search plugin
require content router file
Wrapping feed-link elements with span instead of h5

Declaring feed-links as h5 is semantically incorrect and causes them to be displayed bold and to much space in between
Add "Unfeatured" toolbutton to Article Manager
Fix the jumping toolbar
Hathor icons
Refactor _removeAdminMenus

Changes:
* Pass only the extension ID, not the entire extension row. After all, only the ID is used!
* Always run rebuild() on the menus table, preventing broken nested sets on this table (now you know why this table breaks all the time)
Type hinting
Improve JInstallerAdapterComponent::_buildAdminMenus

Changes:
* Type hinting for $table
* There can be more than one root menu items for a single component if the installation previously failed without rollback (e.g. timeout error)
* The extension ID must always be fetched from the #__extensions table, not the old menu items for the same reasons as above
* Just do not create the menu if $menuElement not exist (it was a TODO item for as long as I remember developing for Joomla!)
* Unnecessary code duplication creating the root menu item
* Refactored the code, moving the actual menu item creation in the _createAdminMenuItem method
* If a submenu already existed with the same parent item the installation would fail. Now we try removing it first, just like we do for the root menu item.
Remove duplicated extension_id records on install / discover_install

If there's a timeout or PHP fatal error during a component's installation there are invalid records left behind in #__extensions and #__menus which prevent further installations. We now detect them and remove them to let the installation proceed.
