That would break existing Makefiles that use the "please take the first
pg_config in the path" feature, which rather make sense (it just means
that you want the extension for your current postgresql).
However you may replace the other appearance with the following:
ifndef PG_CONFIG
PG_CONFIG = pg_config
endif
So as to enable
sh> make PG_CONFIG=/my/manual/path/to/pg_config install
invocations without fear to be overwritten, if some people do not like the
path convention. Otherwise the following does the trick with a temporary
replacement of the PATH environment variable just for one command under
sh-compatible shells:
sh> PATH=/my/manual/path/to:$PATH make install
and is shorter. This could be added to the documentation.
