# of them that has "PGUID" intact, so one can change the value of the
# postgres userid before running initdb in the case of customizing the
# binary release (i.e., fixing up PGUID w/o recompiling the system).
# Those files are copied out as foo.source.  The program newbki(1) can
# be run later to reset the postgres login id (but it must be run before
# initdb is run, or after clearing the data directory with
# cleardbdir(1)). [newbki distributed with v4r2 but not with Postgres95.]
