database you want to connect for all client tools except pg_dumpall. Hence,
you
already know which database has the connection problem. IMO the pg_dumpall
message should inform the database name. My suggestion is:
if (fail_on_error)
{
pg_log_error("database \"%s\": %s",
dbname, PQerrorMessage(conn));
exit_nicely(1);
}
and remove the redundant 'could not connect to database %s' from
scripts/common.c.
