Re: Catalog insertion

I know all you say, but we actually are trying to extend the postresql with new data types, and they must be theorically in the system catalog. Also, these new data types go with some functions for manage it.

We have also implemented this in Oracle and now we want to do this with postgresql.

Any idea it would be welcome. But if this possibility is disallowed by policy, and I use the database as a server, how can I solve it?. Do I have to disallowed all conexions and then do these tasks in the server?.

Ahh, I am working in windows so please take it into account!.

Thank you very much
Carmen.

Oh, you can't do that. It's disallowed by policy. If you want to
create catalogs you need to be in standalone or bootstrap mode
(typically they are created by declaring a src/include/catalog/*.h file
and having it be included in postgres.bki by the genbki script).
