I tried this, but it severely lacks in clarity for someone just getting started in extending pgsql with c. My main gripe really is that while it shows how to write the functions (and I've already read the .h file for all the available v1 features) it lacks in explaining what type is needed for the create function (which is what I'm running squarely into). For example (in my case): I've written a function using PG_GETARGS_CSTRING so now what should the param type be for the create function? char? varchar? text? I'm at the begining phase where it's confusing. I have also tried the contrib tree, but all the programs in there use version 0 coding and I wish to start off on the right foot with pgsql by using the latest method. I have tried searching the archives of the mailing list on finding some explanation about writing code, but all available information seems to be my usual problem when looking for info: tons of technical ref, but too little on getting started to understand the tech ref stuff. Anyone agree? disagree? know of something that I am not seeing?

Start with: http://www.postgresql.org/idocs/index.php?xfunc-c.html Then look at the contrib directory in your source tree for more examples (assuming your source tree is >=7.1). HTH, -- Joe
