My understanding is these procedures are C functions. For examples do the following: List the types already in use and their io-functions as select typname, typinput, typoutput from pg_type ; Then search the source code (*.c files) for <typinput> resp. <typoutput>
There is a box type already. It's box_in and box_out functions can be found in $PGSQLD/src/backend/utils/adt/geo_ops.c HTH Regards, Christoph ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
