Обсуждение: cache question
Can someone explain why there are two network_ops in the pg_opclass table? I am trying to make pg_opclass unique. We have a cache on pg_opclass.opcname, so we clearly have a problem here. Also, is it safe to set opcdeftype to a non-zero value so I can make that index unique too? This stuff confusing. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

Looks like I fixed it. I made on inet_ops and the other cidr_ops. Those names should be unique in there anyway. They are just used when specifying the ops on an index create. The zero entries I just set to dummy values for int24 and int42 because there are no type that match them. I set their typedef to be the same as the ops oid. Hope the sanity check doesn't complain. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

Looks like one is for type inet and the other for type cidr. I'm
still confused about the difference between the two types (hey,
I ain't Paul Vixie) but I suspect we don't really need two entries
in pg_opclass for them --- the types are binary-equivalent according
to parse_coerce.h. If we do need two entries, they should be given
different names.

It's 1:30AM EST ... way past time to be doing serious work, at least
in this time zone ...

Seems like it works now.
