Thread: header files for spi.h/trigger.h

I am in the process of cleaning up the many un-needed includes and  adding includes so each *.h file can is
compile-ableon its own.
 

Speaking of header files, I'm pretty sure that not enough header files
get installed in order to compile something using spi.h/trigger.h
outside the postgresql source tree.  This seems like a problem.

Shouldn't the normal install procedure install everything necessary to
use published postgresql header files?

Cheers,
Brook

Good questions.  I am not touching spi.h because I realize they are used
by client code.

But how much of the stuff that those files are including is really
needed to compile them?  It could be that the right answer is not to
install more headers but to get rid of some #includes in the headers
that are published...

I am doing that will all the other include files, but because spi.h is
used in contrib, I assume they want some stuff auto-included with spi.h.

I sent in a bug-report a while back for all the files that I needed to
include to compile something using spi.h. Lost that message, but here is
the listing of my
current installed include tree.

This was a pretty minimal copy of files accross, just to get something
using spi.h to compile, i.e. trigger.h may need more. I think I copied
the storage directory accross as a whole, but for the rest only the
files that are really required are included. I think you can safely
assume that everything date Jun 19th needs to be added.
