Gilles Darold <gilles@migops.com> writes:Since we have the regexp_like operator I have found that there is two references in the documentation about PostgreSQL lacking of LIKE_REGEX implementation. Here is a patch to fix the documentation. I simply remove the reference to non exist of LIKE_REGEX in PostgreSQL in chapter "9.7.3.8 Differences from XQuery" And try to modify chapter "9.16.2.3. SQL/JSON Regular Expressions" to mention the REGEXP_LIKE operator. For the second fix there should be better wording.I don't think we should change these (yet). regexp_like() is *not* LIKE_REGEX, precisely because it's using a slightly different regular-expression language than what the spec calls for. At some point we may provide a skin for the regexp engine that duplicates the spec's definition, and then we can implement LIKE_REGEX for real.
Thanks for clarifying, I thought it was an oversight.
