Description
dropdb destroys an existing
PostgreSQL database.
The user who executes this command must be a database
superuser or the owner of the database.
dropdb is a shell script wrapper around the
SQL command
via
the PostgreSQL interactive terminal
. Thus, there is nothing
special about dropping databases via this or other methods. This means
that the psql must be found by the script and that
a database server is running at the targeted host. Also, any default
settings and environment variables available to psql
and the libpq front-end library do apply.
