Still trying to fix the bug with inherited check constraints...
I have tried to create a min(oid) aggregate, but when I use it, I get
the message `ERROR: fmgr_info: function 108994: cache lookup failed'.
What is the problem, please?
I created it thus:
create function oid4smaller (oid, oid) returns oid as
'/home/olly/cprogs/oidcompare.so' language 'c';
create aggregate min (basetype = oid, sfunc1 = oid4smaller,
stype1 = oid, stype2 = oid);
The C file is compiled and linked thus (for Linux x86):
$ gcc -o oidcompare.o -c -I/usr/include/postgresql oidcompare.c
$ gcc -shared -o oidcompare.so oidcompare.o
and it says:
#include <postgresql/postgres.h>
Oid oid4smaller(Oid o1, Oid o2) {
return (o1 < o2 ? o1 : o2);
}
Oid oid4larger(Oid o1, Oid o2) {
return (o1 > o2 ? o1 : o2);
}
