PHP 4.0.6 and PostgreSQL

Can anybody else confirm or give reason why with PHP 4.0.6 I am
no-longer able to see detailed error messages?

For instance with PHP 4.0.5 I get the following error message:
Unable to connect to PostgreSQL server: Password authentication failed for user 'foouser'

With PHP 4.0.6 I see:
Unable to connect to PostgreSQL server: (null)

I'll look into it best I can, but I suspect it's a bug.  Thanks in
advance for additional information you guys can provide.
