For example, the function expects 2 arguments, and it's called with 2 arguments: 1 composite type (following this format https://svn.osgeo.org/postgis/spike/wktraster/doc/RFC1-SerializedFormat) and one integer. But PG_NARGS() returns a really big value (16297) when I first check the number of arguments at the beginning of the function. Has sense? The array, if I'm doing things right, is created in the context pointed by fcinfo->flinfo->fn_mcxt. But I'd like to solve "silly" things like the previous before, and to be sure I'm doing things right, in general. Now, I know at least sounds reasonable :-) Many thanks! -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
