[xwiki-users] Problem installing extensions: value too long for type character varying(60000)

Hi List, I just upgraded to XWiki enterprise 5.2.1 and have trouble installing some extensions. When I try to install for instance the "Highlight Macro" extension I'm getting errors during the "install": Applying INSTALL for extension [Highlight Macro 1.3<http://wiki.hosts.itris.nl/xwiki/bin/admin/XWiki/XWikiPreferences?extensionId=vincentmassol%3Ahighlight%2Dmacro&extensionVersion=1.3&extensionNamespace=wiki%3Axwiki&xback=%2Fxwiki%2Fbin%2Fget%2FXWiki%2FInstalledExtensions%3Fsection%3DXWiki.InstalledExtensions&section=XWiki.InstalledExtensions>] on namespace [xwiki <http://wiki.hosts.itris.nl/xwiki/bin/view/Main/WebHome> ] Importing document [Macros.Highlight<http://wiki.hosts.itris.nl/xwiki/bin/view/Macros/Highlight>] in language [en]...
