Обсуждение: Catalog insertion
Hello,
I am trying to include new tables in the PG catalog. Also, I am doing that using the JDBC interface in a Java program. But when I connect to de Postgress template1 database and I execute the CREATE TABLE sentence an error message appears saying: "System catalog modifications are currently disallowed".
Please, I need help to know how to allow to modify the system catalog .
Thank you very much,
Carmen Mtez.

I want to insert new tables in the pg_catalog schema. So I have to execute a common create table sentence like "Create Table pg_catalog.newTable ....", but I am not allowed to do that and I do not know why.
Following I show one of the sentences I execute and the error messages
One of the tables I try to create is:
CREATE TABLE pg_catalog.COL_LIST ( OBJ OID NOT NULL, COL OID NOT NULL, T_TYPE numeric(1) NOT NULL, LEN numeric(2) NOT NULL, COM varchar(100) , PRIMARY KEY (OBJ, COL) , CONSTRAINT LEN_TOO_LONG_IN_COL_LIST CHECK (LEN>=1 AND LEN<=10), CONSTRAINT TYPE_MUST_BE_1_2_o_3 CHECK (T_TYPE=1 OR T_TYPE=2 OR T_TYPE=3))
ERROR: permission denied to create "pg_catalog.col_list"
DETAIL: System catalog modifications are currently disallowed.
Thanks

What CREATE TABLE exactly?

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). -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc.

Why do you think that is a good idea? pg_catalog is for tables used by the system itself, and it's going to take a lot more than a "create table" to teach the system to work with a new catalog. regards, tom lane
Sounds like a Bad Idea(tm) to me. If you want to create extra systemmy tables, then why not set up your own private resources,and put them there instead???

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.

I'd like to use the same system we did with oracle due all the rdbms use a catalog in order to store their system tables and structures.
Using the CREATE TYPE sentence implies a new implementation totally different from the previous one.

We may be able to help you, but we can't if you don't say what you actually want to do (rather than _how_ you think you should do it). Keep in mind that this is a different system from Oracle and things may be done differently. There's a spanish mail list (pgsql-es-ayuda) on this very same server. You may be able to explain yourself better there (and I'll be able to respond more quickly). -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support
