Description

The documentation for built-in relational operator "LIKE" does not clearly define what level of regular expression does it support.

It just says "TRUE if string A matches the SQL simple regular expression B, otherwise FALSE."

I would like a proper definition of "SQL simple regular expression".
I'm also specifically interested in knowing if it support character classes ? etc.

Kindly improve the documentation regarding the "LIKE" operator.
