Well, in a C program, you don't get an error message per se. But I
inserted a call to PQresultErrorMessage() and the result is:

ERROR: CREATE DATABASE: source database "template1" is being accessed by
other users

The circumstances are that in one console, I'm connected in psql to the
template1 database. In a different console (same username) my C program
attempts to connect to a non-existent database. Failing this, it then
attempts to connect to template1 in order to create the other database.
But it can't connect to template1.

This is a Debian 3.0r1 workstation, running PostgreSQL 7.2.1.

P.S. BTW, I'm s*bscr*bed, so no need to echo lists posts offlist to me.
