postgresql patch

[Jason Helfman]

Hi,
  
I was hoping you would be able to consider implementing this PR
(ports/113707) in all applicable versions if possible?
  
This patch makes the postgresql_user a tunable variable.
  
As it stands now, we are maintaining this internally due to this issue,
and would rather release internal maintainership for such a small issue.
  
# diff files/postgresql.in.new files/postgresql.in.orig
36c36
< postgresql_user=${postgresql_user:-"pgsql"}
---
> postgresql_user=pgsql  
  
This patch has been on "over to maintainer" since 2007, and was hoping
you would have a moment to look at this.
  
Thanks so much,
Jason
