I just became aware of the SQL 2016 standard match_recognize feature, which allows for rich pattern matching across groups of rows. It’s a great feature, currently only supported in Oracle.

I can find no evidence it’s ever been discussed here and there’s no mention of it on the PG website.

So: is anyone considering adding this feature?

Do you happen to know if Oracle implemented this before or after 2016?

match_recognize was introduced in Oracle 12.1 which was released in 2013

I think it would be useful, but non-trivial to implement.
