postgres supports a bunch more json operators. See
https://www.postgresql.org/docs/15/functions-json.html
Skipping operators starting with a question mark for now, since those
are hard to distinguish from placeholders without more context.
Postgres supports more generalized locking clauses, for example:
FOR UPDATE OF <table_name> SKIP LOCKED
also, multiple locking clauses. Generalize the parser to support these.
