• Tests include unquoted and quoted table names but lack schema-qualified identifiers. Consider adding cases like "insert into db.events (s) values ('a')" to validate parsing of multi-part names.

            {"insert into `events` (s) values ('a')", 0},

• [nitpick] The generic override enterTableExprIdentifier sets this.table for any table expression, which can unintentionally override the target table in INSERT or other statements. Consider scoping this assignment to specific contexts or resetting the field before reuse.

    public void enterTableExprIdentifier(ClickHouseParser.TableExprIdentifierContext ctx) {

• Using tableId.getText() may include schema qualifiers or quoting syntax that unquoteIdentifier does not fully handle. Add tests and update parsing logic to correctly extract both schema and table names (e.g., db.table).

            this.table = SqlParser.unquoteIdentifier(tableId.getText());

• [nitpick] The buffer size 804800 is a magic number; extracting it into a named constant or adding a comment explaining its origin will improve readability and maintainability.

                .setSocketRcvbuf(804800)
