Instead of bitching out at the person who found the problem. I see.
Maybe I should have said "pretty please". ;)

I'm not really sure - I've had this Alpha here for about 6 months and I
have resulted to using msql since that's about the only thing that will
work efficiently.

I get a core file, but it doesn't tell me squat,

I've actually zeroed in on the problem. It lies somewhere in the
SearchSysCache routine. I'm attempting to debug it now... So far, what I
get is: (Note "[KTH]" is a debug message added by yours truly)
--- SearchSysCache starts here ---
SearchSysCache: [KTH] Hash: 433
SearchSysCache: [KTH] Tuple not found in cache, attempting to find.
SearchSysCache: [KTH] RelationGetRelationName (pg_proc)
SearchSysCache: performing scan (override==0)
SearchSysCache: [KTH] IsBootstrapProcessingMode() is true
SearchSysCache: [KTH] relation check skipped.
SearchSysCache: [KTH] heap_beginscan is okay.
heap_getnext([pg_proc,nkeys=3],backw=0,0x1ffff040) called
heap_getnext returning EOS
SearchSysCache: [KTH] heap_getnext returns null
SearchSysCache: [KTH] tuple not found.
SearchSysCache: [KTH] Heap scan ends.
SearchSysCache: Heap tuple (ntp) is invalid.
ERROR: BuildFuncTupleDesc: function mkoidname(opaque, opaque) does not exist
ERROR: BuildFuncTupleDesc: function mkoidname(opaque, opaque) does not exist
--- End of debug ---
Looks like it lies somewhere in heap_getnext. Heap_getnext is a HUMONGOUS
command, and I'm not about to spend another 2 hours debugging that. ;)
Anyone have any suggestions of a patch for this?
