PATCH for pgconnection.h

I am using the Sun Workshop C 5.0, noticed that I was getting the
following errors:
"pgconnection.h", line 65: Error: string is not defined.
"pgconnection.cc", line 134: Error: string is not defined.
"pgconnection.cc", line 139: Error: Cannot return char* from a function
that should return int.
3 Error(s) detected.

Futher looking noticed that the standard namespace was not being used
for the "string" typedef, so the following patch fixed that for me.
This is for the 6.5 tar release & the 6/24 CVS checkout.
