- .TH DESTROYUSER UNIX 11/05/95 PostgreSQL PostgreSQL
- .SH NAME
- destroyuser - destroy a Postgres user and associated databases
- .SH SYNOPSIS
- .BR destroyuser
- [c
- .BR -a
- system]
- [c
- .BR -h
- host]
- [c
- .BR -p
- port]
- [username]
- .SH DESCRIPTION
- .PP
- .IR Destroyuser
- destroys an existing Postgres user and the databases for which that user
- is database administrator. Only users with *(lqusesuper*(rq set in
- the *(lqpg_shadow*(rq class can destroy new Postgres users. As shipped,
- the user *(lqpostgres*(rq can destroy users.
- .PP
- .IR Destroyuser
- is a shell script that invokes
- .IR psql .
- Hence, a
- .IR postmaster
- process must be running on the database server host before
- .IR destroyuser
- is executed. In addition, the
- .SM PGOPTION
- and
- .SM PGREALM
- environment variables will be passed on to
- .IR psql
- and processed as described in
- .IR psql(1).
- .PP
- The optional argument
- .IR username
- specifies the name of the Postgres user to be destroyed. (The invoker will
- be prompted for a name if none is specified on the command line.)
- .PP
- .IR Destroyuser
- understands the following command-line options:
- .TP 5n
- .BR "-a" " system"
- Specifies an authentication system
- .IR "system"
- to use in connecting to the
- .IR postmaster
- process. This option no longer has any effect.
- .TP
- .BR "-h" " host"
- Specifies the hostname of the machine on which the
- .IR postmaster
- is running. Defaults to using local Unix domain sockets.
- .TP
- .BR "-p" " port"
- Specifies the TCP/IP port or local Unix domain socket file extension
- on which the
- .IR postmaster
- is listening for connections. Defaults to 5432, or the value of the
- .SM PGPORT
- environment variable (if set).
- .SH "INTERACTIVE QUESTIONS"
- .PP
- Once invoked with the above options,
- .IR destroyuser
- will warn you about the databases that will be destroyed in the
- process and permit you to abort the removal of the user if desired.
- .SH "SEE ALSO"
- drop_user(l),
- createuser(1),
- psql(1),
- postmaster(1).
- .SH DIAGNOSTICS
- .TP 5n
- .BI "Error: Failed to connect to backend (host=" "xxx" ", port=" "xxx" ")"
- .IR Destroyuser
- could not attach to the
- .IR postmaster
- process on the specified host and port. If you see this message,
- ensure that the
- .IR postmaster
- is running on the proper host and that you have specified the proper
- port. If your site uses an authentication system, ensure that you
- have obtained the required authentication credentials.
- .TP
- .BI "user *(lq" "username" "*(rq is not in *(lqpg_shadow*(rq"
- You do not have a valid entry in the relation *(lqpg_shadow*(rq and
- cannot do anything with Postgres at all; contact your Postgres site
- administrator.
- .TP

- You do not have permission to delete users; contact your Postgres site
- administrator.

- The user to be removed does not have an entry in the *(lqpg_shadow*(rq
- class.
- .TP
- .BR "database access failed"
- .TP
- .BI "destroydb on" " dbname" " failed - exiting"
- .TP
- .BI "delete of user" " username" " was UNSUCCESSFUL"
- An internal error occurred in
- .IR psql
- or the backend server. Contact your Postgres site administrator to
- ensure that the files and database entries associated with the user
- and his/her associated databases are completely removed.
- .SH NOTE
- The command internally runs fIdrop userfP from fIpsqlfp connected
- to the fItemplate1fP database to perform the operation.
