Missing regexp matching operators

[bgohla]

I have not been able to find Squeal analogs of the PostgreSQL operators ~, ~*, !~ and !~* (https://www.postgresql.org/docs/12/functions-matching.html).

Have I overlooked something, or do I need to implement them myself?

They are currently missing from Squeal. Would def be open to a PR. Looks like should all be the same type as like.

Cool. I guess I'll give it a go.
