#   Makefile for the postgres backend (and the postmaster)
#
# Copyright (c) 1994, Regents of the University of California
#
# Functional notes:
#
#   Parallel make:  
#
#     This make file is set up so that you can do a parallel make (with 
#     the --jobs option of make) and make multiple subdirectories at 
#     once.  
#
#     However, the subdirectory make files are not so careful.
#     Normally, the --jobs option would get passed down to those
#     subdirectory makes, like any other make option, and they would
#     fail.  But there's a trick: Put a value (max number of
#     processes) on the --jobs option, e.g. --jobs=4.  Now, due to a
#     special feature of make, the --jobs option will not get passed
#     to the subdirectory makes.  (make does this because if you only
#     want 4 tasks running, then splitting the subdirectory makes into
#     multiple tasks would violate your wishes).
#
#
#
# Implementation notes:
#
#   We don't use $(LD) for linking.  We use $(CC) instead.  This is because
#   the $(CC) program apparently can do linking too, and it has certain
#   thinks like default options and search paths for libraries set up for 
#   it that the more primitive $(LD) doesn't have.

#
# Installation.
#
# Install the backend program (postgres) to the binary directory and 
# make a link as "postmaster".  Install the bki files, templates, and sample
# files to the library directory.  Install exported headers to the include
# directory (these headers are the minimal ones needed to build loadable
# backend extensions).
#
# (History:  Before Release 2, make install generated a bki.source file
# and then used build parameters to convert it to a bki file, then installed
# that bki file in the /files subdirectory of the default data directory.
# Initdb then used the bki file to generate the database catalog classes.
# That had to change because (1) there can be more than one database system,
# and (2) the parameters of a database system should be set at initdb time,
# not at postgres build time.
