Description
Describe the bug
Consider this SQL in ClickHouse dialect
-- query.txt
RENAME TABLE my_db.app_log_trivial TO my_db.app_log_trivial_tmp_old;
RENAME TABLE my_db.app_log_trivial_tmp TO my_db.app_log_trivial;
DROP TABLE my_db.app_log_trivial_tmp_old;
linted with sqllineage 1.5.3
it gives the error
sqllineage -f query.txt -v

Line 1, Position 1: Found unparsable section: 'RENAME TABLE my_db.app_log_trivial TO m...'
indicating that sqllineage does not understand RENAME operator.
Furthermore, the check against the backend linter sqlfluff
goes OK.
Expected behavior
RENAME is understood and handled correctly.
