I'm setting up phpPgAdmin and I finally get to the point where you
reconfigure pg_hba.conf One of the lines says to reload the values,
type the command pg_ctl reload. I try it as super user, no go, I su
into postgres, it complains:
pg_ctl reload
pg_ctl: no database directory specified and environment variable PGDATA
unset
Try "pg_ctl --help" for more information.
Keeping in mind that I typed just what pga_hba.conf said, was there a
step I was missing (I ended up restarting the server and that worked).

choose an index scan if your joining column's datatypes do not
match
