Wildcards no longer require a backslash in PQL (2023-08-30)

When you’re searching columns in the OLAP table or during attribute selection, and using the % (percent) and _ (underscore) characters as wildcards, you no longer need to use a backslash to escape them. If you search for text that contains the % or _ characters, you now need to prefix them with a backslash to use them literally. See ​LIKE​​ for the function documentation.
