Module query 

db query — pre-flight validate, then run under the request’s optional timeout (threaded to postgres as statement_timeout when set; uncapped when omitted).

Pre-flight rejects shapes the response variant can’t represent:

• multi-statement input (any unquoted ; followed by non-empty non-comment content),
• COPY ... TO STDOUT|STDIN (no FE/BE protocol path for it),
• transaction control verbs (BEGIN, START, COMMIT, END, ROLLBACK, SAVEPOINT, RELEASE) — the handler runs the user query inside its own read-only tx and these would collide.
