// I know what you're thinking: you're wondering "why doesn't this use $1
|
|
// and pass variadic parameters to ExecContext?" — the answer is because
|
|
// PostgreSQL doesn't expect the table name to be specified as a substituted
|
|
// argument in that way so it results in a syntax error in the query.
