Hi, just for fun, I wrote a little postgresql contrib, who has a C function called myfun inside it. The function myfun returns a value , now I return a cstring type value, and it works fine if I run from psql shell:
select value from myfun(paramteres); but I can't do an insert like: insert (charfield) select value from myfun(paramteres); becuse I have an error, exactly casting error. I want that myfun returns a char,varchar, or text type. Where I can find more documentation about differences between cstring,char,text etc...?
