The examples assume that there is a database named test and you
have the necessary rights to access it without password (probably the
database is on a server at the local machine) as the default user,
i.e. the user with the same name as your current operating system
account.
Each example contains code for cleaning up, but, for more clarity, the
cleanup is not enforced with Octaves unwind_protect or with an
SQL transaction. If something goes wrong, you can drop the database
test – this should assure purging any created large objects.
You can also type demo pq_connect to access some demo code. But
it is possibly more difficult to read. test pq_connect runs some
functionality tests. The preconditions (access to a database named
test) are the same as for the code in the current section.
