I kinda doubt that a huge array of tsquery's is a realistic scenario.

I don't think so. Maybe there's an argument that 1024 is too large,
but I would say that 32 is much too small. Also there are plenty of
other places using the default buffer length without worrying about
this. It seems unlikely to me that quibbling over the value is really
going to be a productive use of brain cells.
