• Fix to avoid truncated data with XHGui\Saver\PdoSaver

1) XHGui\Test\Controller\RunTest::testIndexEmpty
PDOException: SQLSTATE[42704]: Undefined object: 7 ERROR:  type "longtext" does not exist
LINE 4:               "profile"          LONGTEXT       NOT NULL,

looks like this is database dependent, so far we've avoided abstracting database type:

I've added the driver name to the repository class:

• https://github.com/perftools/xhgui/pull/438

so this could be evaluated to make driver-specific changes

Rebased and changed target branch, so pay attention to update your local branch first if you add more commits to this branch

@mkeromen close, since you're no longer interested in this?

@glensc This is actually rather important since json_decode() silently returns null on truncated data. That means no error and empty results in the callgraph. Harder to debug.

Closing, as seems the original author is not interested in finishing this.

@glensc What about my comment? Do you want me to open a new pull request?
