portupgrade postgresql-7.3.4_1

[Robert Fitzpatrick]

Trying to do the portupgrade of postgresql on my FreeBSD 5.2.1 box. When
I try a 'pkg_delete postgresql-7.3.4_1', it has dependents and says
cannot be deinstalled. How do I handle this port upgrade?

esmtp# pkg_delete postgresql-7.3.4_1
pkg_delete: package 'postgresql-7.3.4_1' is required by these other
packages
and may not be deinstalled:
nagios-1.1_3
nagios-plugins-1.3.1
phppgadmin-3.0.1
postfix-2.0.16,1
