PGHOME defaults inconsistent...

[Richard PALO <richard.palo%free.fr@localhost>]

There seems to be an inconsistency in postgres defaults, namely with 
PGHOME. From mk/defaults/mk.conf:
> PGGROUP?=       pgsql
> PGUSER?=        pgsql
> PGHOME?=        ${PREFIX}/${PGUSER}

But in the diverse postgres server Makefiles:
> postgresql84-server/Makefile:PGHOME?=           ${VARBASE}/${PGUSER}
> postgresql90-server/Makefile:PGHOME?=           ${VARBASE}/${PGUSER}
> postgresql91-server/Makefile:PGHOME?=           ${PREFIX}/${PGUSER}
> postgresql92-server/Makefile:PGHOME?=           ${VARBASE}/${PGUSER}
> postgresql93-server/Makefile:PGHOME?=           ${VARBASE}/${PGUSER}

Seems that defaults/mk.conf should use ${VARBASE} and that the 
p*-server/Makefiles should remove PGHOME/PGUSER/PGGROUP definitions in 
order to only refer either to defaults or to the eventually overridden 
values set in the etc/mk.conf.

Observations?
