Test, validate and match regular expressions
Matches Trino SQL statements that invoke the kill_query system procedure, in either uppercase or lowercase form (e.g., 'CALL system.runtime.kill_query' or 'call "system"."runtime"."kill_query"'). Useful for detecting or filtering queries intended to terminate running sessions in a Trino cluster. Supports optional double quotes around the catalog, schema, and procedure names, and uses gm flags for multiline/global matching. Note the unescaped dots match any character, not just literal periods.
