- Fix typos (chmod being used instead of chown in %postun web and
pgadmin4 used in the service file for User/Group keys instead of
pgadmin)

- the system wide service does not need to run as root. switch to
user/group pgadmin

- Update to 4.30
- Features:
- ERD Tool (Beta): The Entity-Relationship Diagram (ERD) tool
is a database design tool that provides a graphical
representation of database tables, columns, and
inter-relationships. You can use the ERD tool to design a new
schema and generate the SQL required to create it, or to
reverse engineer and diagram an existing database schema.
- Kerberos support is added in pgAdmin 4 using SPNEGO for
logging into pgAdmin, similar to the existing LDAP and
"internal" options. Note that support for logging into
database servers using Kerberos is not included in this
release, but will be added in a future version.
- Add a container option (PGADMIN_DISABLE_POSTFIX) to disable
the Postfix server: Postfix (like other MTAs) must start as
user 'root', and the pgAdmin container achieves this using
'sudo'. Whilst that works well in most environments, it can
cause problems in some. This option allows you to completely
disable Postfix to avoid these issues, though you will need
to configure an external mail server to be used to send
password reset emails.
- Bugs/Housekeeping:
- Improve the explain plan details by showing a popup instead
