Is this the kind of thing you mean?
#include "postgres.h"
#include "fmgr.h"
extern Datum pg_reset_stats(PG_FUNCTION_ARGS);
PG_FUNCTION_INFO_V1(pg_reset_stats);
Datum
pg_reset_stats(PG_FUNCTION_ARGS)
{ void pgstat_reset_counters(void);
PG_RETURN_VOID();
}
With this code I get this:
test=# select pg_reset_stats();
ERROR: Unable to look up type id 0
I'm creating it like this:
create or replace function pg_reset_stats() returns opaque as
'/home/chriskl/local/lib/postgresql/pg_reset_stats.so' language 'C';
Is it something to do with the return type being declared wrongly?
Hmm...the manual indicates that opaque functions cannot be called directly -
so what the heck do I do?
Also, where would I put this function in the main postgres source and how
would I modify initdb?
