Review comment:
This looks like the
https://www.postgresql.org/docs/current/functions-matching.html#FUNCTIONS-POSIX-TABLE
functionality which uses an Operator `~` to instead of a function. I think the
kernel names are fine but it would be nice if we could retain the postgres
semantics in order to achieve as much compatibility as possible.
