Dumping pg_shadow and pg_database as SQL using pg_dump

I'd like to save the list of users, groups, and databases regularly to a
separate file (just in case). The output of pg_dumpall suffices for my need:

=============== =============== ===
DELETE FROM pg_shadow WHERE usesysid <> (SELECT datdba FROM pg_database
WHERE datname = 'template0');

DELETE FROM pg_group;

=============== =============== ===

But can I get these with pg_dump?

Is there a way, having a user entered username and password, to select a single row from pg_shadow which is using md5 password encryption? I'm currently authenticating web users (.asp page) with our own user table that uses crypt() to store passwords. I'd like to remove our 'redundant' user table and use pg_shadow. The authentication function I'm using is included in the attachment... Thanks. <<auth_user.txt>> William Harazim,...

Hi, I'm having some problems with pg_database -system table. It lost all of it's contents while database was running. It's actually still running but I don't know what to do because I'm not sure if it will start up at all after shutdown. I noticed the problem while trying to use pg_dump: tuner@xyzzy:~$ /usr/local/pgsql/bin/pg_dump -Ugalleria galleria pg_dump: missing pg_database entry for database "galleria"

I read that the password hash in pg_shadow is salted with username. Is this still the case? If so, since probably 99% of all PostgreSQL has "postgres" as the superuser name, wouldn't it be better to use standard Unix/Apache MD5 hash instead? -- dave ---------------------------(end of broadcast)---------------------------

Hi All, I'm wonder if there is any possibility to modify a users password by updating the pg_shadow table. I'd like to ensure that when the user modifies his/her http password (htpasswd) than his database password also changes. It is important to have the same password for both services. I plan to do it from php. Is there any way to do so? Thans,

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
