Hi mentors and hackers,
I am working on providing a new plugin where creates new data type
(thrift). What I am currently planning is to translate cstring to byte for
thrift_in functions. The cstring should be json format. When I looking at
json helper functions I find the header
./include/server/utils/json.h
where all functions have the signature of Datum
function(PG_FUNCTION_ARGS).This signature causes extra overhead when
writing the code because I need to convert my intermediate variables to the
required format. Wondering are there any json helpers that are used by
postgresql and plugins can directly call?
Thanks Charles
