Bug reference:      7874
Logged by:          Joe Van Dyk
Email address:      joe@tanga.com
PostgreSQL version: 9.2.1
Operating system:   OSX, Linux
Description:        =


If I run:
   alter database foo set my.name =3D 'joe';

that GUC isn't available inside backups of that database.

It does show up when doing "pg_dumpall -s". =


It does *not* show up when doing "pg_dumpall -g"


$ createdb foo
$ psql foo
psql (9.2.1)

foo=3D# alter database foo set my.name =3D 'joe';
ALTER DATABASE

foo=3D# \q

$ pg_dump foo > foo.sql

$ cat foo.sql
--
-- PostgreSQL database dump

SET statement_timeout =3D 0;
SET client_encoding =3D 'UTF8';
SET standard_conforming_strings =3D on;
SET check_function_bodies =3D false;
SET client_min_messages =3D warning;

This is a TODO:

    https://wiki.postgresql.org/wiki/Todo#ALTER

    Refactor handling of database attributes between pg_dump and pg_dumpall

        Currently only pg_dumpall emits database attributes, such as ALTER
    DATABASE SET commands and database-level GRANTs. Many people wish that
    pg_dump would do that. One proposal is to let pg_dump issue such
    commands if the -C switch was used, but it's unclear whether that will
    satisfy the demand.
