Graphql-engine: posix regular expression operator

[tirumaraiselvan]

Currently, for regex match operations we have _similar and _nsimilar operators. These are based on Postgres' SIMILAR operator which is based on SQL standard definition of regular expression.

Postgres also has POSIX regular expression which might be more common in usage: https://www.postgresql.org/docs/current/functions-matching.html#FUNCTIONS-POSIX-REGEXP

We can add these operators to permissions and graphql schema.

Is there some progress on that?
It looks like nobody is interested in searching with regular expressions? Is there another way to do it?

We wanted to use SIMILAR %(b|d)% but it is not key sensitive and ILIKE doesn't look to support regular expressions.

Would make a text search of users against both their first and last names much more straightforward!

Is there any progress on this issue? It would help a lot in making searches faster.

We cannot use lookAhead properly with SIMILAR TO
