Trim trailing semicolon after normalization.
The motivation behind this change is that
pg_stat_statementsnormalizes queries without semicolon, whilepg_stat_activityretains the exact query that's executed.Since the semicolon (;) at the end of a SQL statement is optional and doesn't affect the "meaning" of the query, we want to left it off to simplify and standardize the pattern post normalization.
