Hi,
I defined a new type, and it is essential that I am able to use it in
an index. This seems to require a bit more than just having the
comparison operators. On the create index page it seems that it is
necessary to define an *_ops class for the new type, but I have no idea
how I go about this. I have looked at the folowing system tables
pg_am
pg_amop
pg_opclass
pg_operator
but have no idea how I go about inserting the new type into these
classes.
I have operators for <, <=, =, <>, > and >= defined and they work fine,
so I think it should be possible to define a btree. I did not define
HASH or any of that stuff when defining the operators as I wasn't too
sure what that implied.
I'd really appreciate any hints on this one.
Thanks in advance,
Adriaan
