.SH DESCRIPTION
|
|
.IR Createdb
|
|
creates a new database. The person who executes this command becomes
|
|
the database administrator, or DBA, for this database and is the only
|
|
person, other than the Postgres super-user, who can destroy it.
|
|
.PP
|
|
.IR Createdb
|
|
is a shell script that invokes
|
|
.IR psql .
|
|
Hence, a
|
|
.IR postmaster
|
|
process must be running on the database server host before
|
|
.IR createdb
|
|
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 created. The name must be
|
|
unique among all Postgres databases.
|
|
.IR Dbname
|
|
defaults to the value of the
|
|
.SM USER
|
|
environment variable.
|
|
.PP
|
|
.IR Createdb
|
|
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).
|
|
.SH EXAMPLES
|
|
.nf
|
|
# create 5432 demo database
|
|
createdb demo
|
|
.fi
|

# create the demo database using the postmaster on host eden,
|
|
# port using the Kerberos authentication system.

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.

|
|
.BI "user \*(lq" "username" "\*(rq is not in \*(lqpg_user\*(rq"
|
|
You do not have a valid entry in the relation \*(lqpg_user\*(rq and
|
|
cannot do anything with Postgres at all; contact your Postgres site
|
|
administrator.
|
|
.TP
|
|
.BI "user \*(lq" "username" "\*(rq is not allowed to create/destroy databases"
|
|
You do not have permission to create new databases; contact your Postgres

.IR psql
|
|
or the backend server. Ensure that your Postgres site administrator has
|
|
properly installed Postgres and initialized the site with
|
|
.IR initdb .
