I doubt that's a problem. Parse analysis won't remove information from the query - otherwise it'll not be available for the actual planning and execution ;)
- snaga 11y ago> Parse analysis won't remove information from the query That's right. PostgreSQL's parse analysis keeps a statement structure with token-by-token in the parse tree, and PostgreSQL's query jumbling calculates a hash value from the parse tree. So, it's possible to find something strange in the statement(s) if someone attempts to cheat.
