If you or anyone reading this can put together a working C trigger example
with a test table and compile and trigger load procedure, I'd like to have it
to play with! I've been trying to use the examples in the docs and the ones
in contrib/spi, but with no luck. I'm using 7.0.3. I notice that the delev
docs have a different C trigger example than the 7.0 docs. I don't know what
the differences are, one returns a HeapTuple and the other a Datum (a
unsigned long)?
Anyhow, some more detailed, up-to-date, docs on some of this would be nice.
If I can learn these structs etc for C triggers, I'll try to write some HTML
page about it how it all works in detail.
