Thread: How to make a map in pg kernel?

Hi, I’m writing some kernel codes in pg15, and now I need to make a map struct, I know c-lang doesn’t support this, so
doespg support an internal struct? Hopefully your replies.

PostgreSQL has hash tables:

This is not exactly a map struct. But it might be suitable for your case.
