Function looksMultiStatement

internal/identity/migrate.go:280–286

looksMultiStatement returns true if body appears to contain more than one SQL statement. Not a full parser — handles the common shapes (line comments, block comments, single-quoted strings) and catches the case the no-transaction directive is most likely to trip on: a user writing `SET something; CR

(body string)

// those would need a real parser. The directive isn't intended for
// those cases anyway — it's for single CONCURRENTLY-class statements.
func looksMultiStatement(body string) bool {
	stripped := stripSQLCommentsAndStrings(body)
	// A single statement (with optional trailing whitespace + semicolon)
	// has zero ';' after we trim. A multi-statement script has 1+.
	stripped = strings.TrimRight(stripped, "; \t\n\r")
	return strings.Contains(stripped, ";")
}

// stripSQLCommentsAndStrings removes -- line comments, /* */ block
// comments, and '...' single-quoted strings from the body. Used by
