It's useless without the rest of the backend infrastructure, including
elog error recovery and a cooperative main loop. You could certainly
reuse the code in a different application if you were willing to adopt
Postgres' memory management and error handling approaches
lock-stock-and-barrel, but I don't think you could be selective about
it. For a library that has to work inside a not-so-cooperative
application, the idea is a nonstarter.
