When I started this patch, I thought that WITH_POSTGRESQL was used more often
then WITH_POSTGRES in the ports tree. After finishing half of the patch I did
some tests to make sure, and it looks like WITH_POSTGRES is used in 11
different ports, whereas WITH_POSTGRESQL is used in only 10 different ports.
However, I think that WITH_POSTGRESQL should be favoured, because the
port/product is named/advertised as PostgreSQL ( http://www.postgresql.org/ ).
Therefore I propose this patch.
Even if it won't be committed, there is an error in lang/pike72, which checks
for the existance of libpq.so.2, but depends on libpq.so.3 if WITH_POSTGRES
Ties in to ports/71177
Moving to ports/73843 for repocopy, patch, and exp build run.
