RE: [EXTERNAL] Re: CREATE SERVER makes 2 entries in the dictionary - Mailing list pgsql-bugs

Hi,

I’ve connected to a test database, executed the create server syntax successfully. While connected to the test database, I see results in the pg_foreign_server table. Changing to the postgres database, I see the same results in the postgres database, but with a different OID. Furthermore, alterations can be made independently to each server based on which db one is connected to.

 

Seems to me this is a bug:

Pg

 

postgres@tsthpx01:~/work/tsdb=> psql -dtsdb

Pager usage is off.

Type "help" for help.

You are now connected to database "postgres" as user "postgres".
