|
|
.BR destroydb

|
|
system]
|
|
[\c

.SH DESCRIPTION
|
|
.IR Destroydb
|
|
destroys an existing database. To execute this command, the user must
|
|
be the database administrator, or DBA, for this database.
|
|
The program runs silently; no confirmation message will be displayed.
|
|
After the database is destroyed, a Unix shell prompt will reappear.
|
|
.PP
|
|
.IR Destroydb
|
|
is a shell script that invokes
|
|
.IR psql .
|
|
Hence, a
|
|
.IR postmaster
|
|
process must be running on the database server host before
|
|
.IR destroydb
|
|
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 dbname
|
|
specifies the name of the database to be destroyed. All references to
|
|
the database are removed, including the directory containing this
|
|
database and its associated files.
|
|
.IR Dbname
|
|
defaults to the value of the
|
|
.SM USER
|
|
environment variable.
|
|
.PP
|
|
.IR Destroydb
|
|
understands the following command-line options:
|
|
.TP 5n
|
|
.BR "-a" " system"
|
|
Specifies an authentication system
|
|
.IR "system"
|
|
(see
|
|
.IR introduction (1))
|
|
to use in connecting to the
|
|
.IR postmaster
|
|
process. The default is site-specific.
|
|
.TP
|
|
.BR "-h" " host"
|
|
Specifies the hostname of the machine on which the
|
|
.IR postmaster
|
|
is running. Defaults to the name of the local host, or the value of
|
|
the
|
|
.SM PGHOST
|
|
environment variable (if set).
|
|
.TP
|
|
.BR "-p" " port"
|
|
Specifies the Internet TCP port on which the
|
|
.IR postmaster
|
|
is listening for connections. Defaults to 5432, or the value of the
|
|
.SM PGPORT
|
|
environment variable (if set).
|
|
