PgSQL bug?

I have just attempted a clean install of shiny, new 4.7.

When I came to import 'database.pgsql' into PgSQL 8.0.7, however, phpPgAdmin threw the following error message:

SQL error:
ERROR:  syntax error at or near ")" at character 32

In statement:
SELECT COUNT(*) AS total FROM () AS sub

That was the entire message; 'expand' did not reveal any more.

I hope this helps someone debug something somewhere - I'm going to try again with MySQL!
